AB  - Surface plasmon polaritons (SPP) are electromagnetic waves bound by the collective oscillations of free carrier plasma to the surface of a conductor surrounded by dielectric. These waves can be localized, concentrated or manipulated simply by processing the conductor surface. The choice of a convenient conductor is quite limited by the availability of natural materials and strong absorption losses associated with free electron plasma. For this reason new alternative plasmonic materials are actively being researched and developed. Most common approaches to this problem include doping of nonmetallic materials and fabrication of metal-dielectric nanocomposite metamaterials. In this contribution we perform an analysis of the suitability of the use of the heterometallic multilayers consisting of copper and nickel. Copper is an excellent plasmonic material, but the problem is formation of natural copper oxides on the surface. Therefore for this purpose a layer of nickel is used as a protection against oxidation of copper. Laminate composite structures of alternating nanocrystalline nickel and copper films on a cold-rolled polycrystalline copper foils were fabricated by electrochemical deposition technique. We simulated the electromagnetic properties of subwavelength Cu/Ni multilayers by the 2D finite element method using realistic material parameters to assess different electromagnetic modes. Our results show that the pair Cu/Ni can be viewed as an alternative tailorable plasmonic material. It has also been shown that it is possible to fabricate plasmonic structures without applying any complex lithographic processes.

AB  - In this work we review methods to decrease the optical absorption losses in metamaterials. The practical interest for metamaterials is huge, but the possible applications are severely limited by their high inherent optical absorption in the metal parts. We consider the possibilities to fabricate metamaterial with a decreased metal volume fraction, the application of alternative lower-loss plasmonic materials instead of the customary utilized noble metals, the use of all-dielectric, high refractive index contrast subwavelength nanocomposites. Finally, we dedicate our attention to various methods to optimize the frequency dispersion in metamaterials by changing their geometry and composition in order to reach lower absorption, which includes the use of the hypercrystals. The final goal is to widen the range of different metamaterialbased devices and structures, including those belonging to transformation optics. Maybe the most important among them is the fabrication of a novel generation of all-optical or hybrid optical/electronic integrated circuits that would operate at optical frequencies and at the same time would offer a packaging density and complexity of the contemporary integrated circuits, owing to the strong localization of electromagnetic fields enabled by plasmonics.

AB  - Plasmonic nanocomposites are a new class of
materials that offers unprecedented opportunities to tailor the
optical response, including the possibility to design their spectral
and spatial dispersion at will. This includes the optical
parameters rarely or never met in nature, which opens a path
toward plasmonic metamaterials and the wide new area of
transformation optics. Responsible for such a unique behavior
are bound surface modes propagating along interfaces between
materials with different signs of relative dielectric permittivity
known as surface plasmon polaritons (SPP). Most metals possess
negative relative permittivity in optical range due to the existence
of free electron plasma. However, they also exhibit large
absorption losses and are bound to a given spectral range defined
by the metal itself, which is the reason why alternative plasmonic
materials are being actively sought upon. One possible way to
extend the toolbox of available materials is to use alternating
metal-dielectric or metal-metal layers – the one-dimensional
plasmonic crystals. Typically gold and silver are used for the
metal part due to their large conductance and generally
favorable properties. In this contribution we perform an analysis
of the suitability of the use of copper for plasmonic
nanocomposites. Its oxidation, the main barricade towards its
more widespread use in plasmonics, is avoided by combining it
with nickel. We utilize ab initio analysis by 2D finite element
modeling and realistic material parameters to assess different
electromagnetic modes. Tailorability of the response is attained
by simple changing of the Cu to Ni fill factor. The analyzed CuNi plasmonic crystals are convenient for simple, low cost
biochemical sensors and superabsorbers.

AB  - Plasmonics and optical metamaterials offer possibilities for numerous applications in different fields, from transformation optics and chemical sensing to merging the beneficial properties of electronic and optical circuits. Crucial for their function are interfaces between materials of which one has to exhibit negative value of relative dielectric permittivity due to the existence of free electron plasma. However, the choice of convenient materials is rather limited and their performance is severely impaired by strong absorption losses. This is the reason why alternative plasmonic media are currently of an increasing interest. In this contribution we consider one such medium, the heterometallic multilayer consisting of copper and
nickel. Copper is an excellent plasmonic material, but needs protection against surface oxidation, a role fulfilled by nickel layers which simultaneously form interfaces supporting surface waves. We describe our proposed heterometallics and consider their electromagnetic properties and experimental fabrication. Ab initio numerical simulations were done using the finite element method for Cu-Ni multilayers on a copper substrate. Laminate composite structures of alternately electrodeposited nanocrystalline Ni and Cu films on cold-rolled polycrystalline copper substrates were fabricated. Highly-densified parallel interfaces can be obtained by depositing layers at a very narrow
spacing. Our results show that Cu-Ni pairs are a viable
alternative to conventional plasmonic media, while the
electrodeposition approach offers acceptable structural and electromagnetic parameters with large area and good uniformity at a low cost.

We use the copper-nickel multilayers. Copper is a good plasmonic material, but not widely used due to surface oxidation impairing its electromagnetic properties over time. The layers of nickel, also a plasmonic material, serve a dual purpose of being a protection against copper oxidation and ensuring formation of surface waves at the alternating interfaces between the two materials. At the same time, the multilayers serve as couplers between the propagating and the surface waves.

AB  - The main problems with plasmonics for devices are connected with its very nature implying the need to use free electron conductors, mostly good metals like silver or gold. The choice of natural materials and thus their operating ranges, as defined by their plasma frequency, is rather limited. Also, absorption losses in good conductors are quite high. Because of that alternative plasmonic materials are of increasing interest. In this contribution we consider the possibility to design plasmonic crystals incorporating a pair of plasmonic materials (all-metal plasmonic crystals). For the sake of technological simplicity, we limit ourselves to one-dimensional structures with a pair of alternating layers with subwavelength periodicity. Such structures behave as strongly anisotropic effective media tailorable by design. In other words, instead of considering waveguiding in usual IMI (insulator-metal-insulator) and MIM (metal-insulator-metal) we investigate MMM (metal-metal-metal) and generally PPP (plasmonic-plasmonic-plasmonic) structures. For the plasmonic material pair we choose copper and nickel. The properties of Cu as a plasmonic material are excellent, however it oxidizes when exposed to atmosphere. Besides serving as the second plasmonic material, Ni also protects Cu layers against corrosion. Electromagnetic simulations to obtain optical properties of our all metal plasmonic crystal were performed using the finite element method.

AB  - We analyze the fundamental properties of optical waves referred to as Tamm plasmon modes (TPMs) which are tied to the interface of a semi-infinite two-phase metallodielectric superlattice with an arbitrary homogeneous capping medium. Such modes offer new ways of achieving high electromagnetic field localization and spontaneous emission enhancement in the vicinity of the interface in conjunction with absorption loss management, which is crucial for future applications. The homointerface, formed when the capping medium has the same permittivity as one of the superlattice constituents, is found to support a TPM whose dispersion overlaps the single-interface surface plasmon polariton (SPP) dispersion but which has a cut off at the topological transition point. In contrast, a heterointerface formed for an arbitrary capping medium, is found to support multiple TPMs whose origin can be traced by considering the interaction between a single-interface SPP and the homointerface TPM burried under the top layer of the superlattice. By carrying out a systematic comparison between TPMs and single-interface SPPs, we find that the deviations are most pronounced in the vicinity of the transition frequency for superlattices in which dielectric layers are thicker than metallic ones.

AB  - We investigate, both theoretically and numerically, a graphene-coated nano-cylinder illuminated by a plane electromagnetic wave in the far-infrared range of frequencies. We have derived an analytical formula that enables fast evaluation of the spectral window with a substantial reduction in scattering efficiency for a sufficiently thin cylinder. This polarization-dependent effect leads to tunable resonant invisibility that can be achieved via modification of graphene chemical potential monitored by the gate voltage. A multi-frequency cloaking mechanism based on dimer coated nanowires is also discussed in detail.

AB  - We consider the possibility to use plasmonics to enhance light trapping in such semiconductor detectors as solar cells and infrared detectors for night vision. Plasmonic structures can transform propagating electromagnetic waves into evanescent waves with the local density of states vastly increased within subwavelength volumes compared to the free space, thus surpassing the conventional methods for photon management. We show how one may utilize plasmonic nanoparticles both to squeeze the optical field into the active region and to increase the optical path by Mie scattering, apply ordered plasmonic nanocomposites (subwavelength plasmonic crystals or plasmonic metamaterials), or design nanoantennas to maximize absorption within the detector. We show that many approaches used for solar cells can be also utilized in infrared range if different redshifting strategies are applied.

AB  - In this paper we propose a possible use of butterfly scales as templates for ordered 2D or 3D nanophotonic materials, with complexity not easily reproducible by conventional micro/nanofabrication methods. Functionalization through laminar nanocompositing is utilized to impart novel properties to the biological scaffold. An extremely wide variability of butterfly scale forms, shapes, sizes and fine structures is observed in nature, many of them already possessing peculiar optical properties. Their nanophotonic functionalization ensures a large choice of forms and functions, including enhanced light localization, light and plasmon waveguiding and general metamaterial behavior, to mention a few. We show that one is able to achieve a combination of plasmonics and bionics, resulting in functionalities seldom if ever met in nature. As an illustration we have analyzed the photonic properties of the nanostructured scales on the wings of Purple Emperor butterflies Apatura ilia, Apatura iris and Sasakia charonda. Their intricate nanometer-sized structures produce remarkable ultraviolet-blue iridescence, spectrally and directionally narrow. We present our analysis of their plasmonic/nanophotonic functionalization including preliminary calculations and initial experimental results. As a simple example, we used radiofrequent sputtering to produce nanoaperture-based plasmonic structures at a fraction of the cost and necessary engineering efforts compared to the conventional top-down methods. We conclude that the described pathway to biomimetic plasmonics offers potentials for significant expansion of the nanophotonic and nanoplasmonic material toolbox.

AB  - We analyzed surface-wave propagation that takes place at the boundary between a semi-infinite dielectric and a multilayered metamaterial, the latter with indefinite permittivity and cut normally to the layers. Known hyperbolization of the dispersion curve is discussed within distinct spectral regimes, including the role of the surrounding material. Hybridization of surface waves enable tighter confinement near the interface in comparison with pure-TM surface-plasmon polaritons. We demonstrate that the effective-medium approach deviates severely in practical implementations. By using the finite-element method, we predict the existence of long-range oblique surface waves.

AB  - We investigate the existence and dispersion characteristics of surface waves that propagate at an interface between a metal-dielectric superlattice and an isotropic dielectric. Within the long-wavelength limit, when the effective-medium (EM) approximation is valid, the superlattice behaves like a uniaxial plasmonic crystal with the main optical axes perpendicular to the metal-dielectric interfaces. We demonstrate that if such a semi-infinite plasmonic crystal is cut normally to the layer interfaces and brought into contact with a semi-infinite dielectric, a new type of surface mode can appear. Such modes can propagate obliquely to the optical axes if favorable conditions regarding the thickness of the layers and the dielectric permittivities of the constituent materials are met. We show that losses within the metallic layers can be substantially reduced by making the layers sufficiently thin. At the same time, a dramatic enlargement of the range of angles for oblique propagation of the new surface modes is observed. This can lead, however, to field non-locality and consequently to failure of the EM approximation.

AB  - Due to their high specific detectivities and large response speeds, photodetectors based on narrow-bandgap semiconductors like indium-antimonide and mercury cadmium telluride are indispensable for mid- and far-infrared wavelength ranges. Their response is directly proportional to the infrared radiation flux introduced to the detector active area. Thus various photon management techniques are of crucial importance for enhancing their performance. This work analyzes the use of subwavelength nanophotonic structures with antireflective properties. It considers surface-based diffractive optical structure that can be produced by micromachining and nanofabrication. The first part of the consideration is dedicated to all-dielectric subwavelength arrays with 1D and 2D periodicity, which effectively behave as impedance-matching structures with graded effective refractive index. The consideration is then expanded to metal-dielectric structures, especially those belonging to the class of the so-called plasmonic ultra-absorbers. Technologies available in Serbia are then investigated technologies for the fabrication of the dielectric and metaldielectric subwavelength antireflective structures for the infrared, including isotropic and anisotropic etching of surface reliefs and ultrathin-film deposition techniques. It is concluded that diffractive dielectric and plasmonic structures offer a novel degree of freedom in optimization of infrared semiconductor photodetectors.

AB  - In this paper we review some metasurfaces with negative values of effective refractive index, as scaffolds for a new generation of surface plasmon polariton-based biological or chemical sensors. The electromagnetic properties of a metasurface may be tuned by its full immersion into analyte, or by the adsorption of a thin layer on it, both of which change its properties as a plasmonic guide. We consider various simple forms of plasmonic crystals suitable for this purpose. We start with the basic case of a freestanding, electromagnetically symmetrical plasmonic slab and analyze different ultrathin, multilayer structures, to finally consider some two-dimensional "wallpaper" geometries like split ring resonator arrays and fishnet structures. A part of the text is dedicated to the possibility of multifunctionalization where a metasurface structure is simultaneously utilized both for sensing and for selectivity enhancement. Finally we give an overview of surface-bound intrinsic electromagnetic noise phenomena that limits the ultimate performance of a metasurfaces sensor.

AB  - We study the properties of electromagnetic waves
propagating along the waveguides with a periodic core created
by alternating metal and dielectric layers, the so-called
quasi-one-dimensional plasmonic crystal waveguides. Such
waveguides can be symmetric or asymmetric, depending on
the cladding or substrate material properties, as well as on
the termination of the periodic structure.We analyze the dispersion
characteristics as well as the profiles of the guided
modes for several types of waveguide structure.
