Fishnet-Based Metamaterials: Spectral Tuning Through Adsorption Mechanism
(Polish Academy of Sciences, 2009)
In this work we consider the tuning of spectral reflectance of fishnet metamaterials with circular or elliptic apertures due to the presence of dielectric analyte adsorbed within the pores of the dielectric part. We simulated ...
Vacuum Fluctuations in Optical Metamaterials Containing Nonlinear Dielectrics
(Polish Academy of Sciences, 2009)
We investigated the influence of zero-point fluctuations (vacuum fluctuations, optical quantum noise) to the optical response of electromagnetic metamaterials containing dielectrics with third-order Kerr-like nonlinearity. ...
Surface plasmon - Polariton assisted metal-dielectric multilayers as passband filters for ultraviolet range
(Polish Academy of Sciences, 2007)
We designed and fabricated metal-dielectric multilayers intended for passband filters in the ultraviolet range. We determined the dispersion characteristics by the Bloch approach to evanescent wave resonant coupling and ...
Synthesis, Characterization and Application of Al,Fe-Pillared Clays
(Polish Academy of Sciences, 2009)
Al,Fe-pillared clay was synthesized from domestic clay from Bogovina according to a common procedure: grinding, sieving, Na exchange, pillaring, drying and calcination. Two synthesized samples differing only in calcining ...
Thermomagnetic behaviour and microstructure of a rapidly quenched Nd4.5Fe77B18.5 alloy
(Polish Academy of Sciences, 2008)
Changes in the phase composition and crystallite size, as well as changes in the magnetic behaviour of Nd4.5Fe77B18.5 alloy, caused by thermomagnetic measurements, was observed in regard of the optimal magnetic state of ...
Structure and magnetic properties of nanocrystalline NiFe2O 4 prepared via precipitation route
(Polish Academy of Sciences, 2014)
Nanocrystalline Ni-ferrite was synthesized by modified precipitation method in which soluble starch is used as dispersing agent and Na2CO 3 as a precipitating agent. NiSO4-6H2O and Fe(NO3)3-9H2O were used as precursors for ...
NdFeB permanent magnets with various Nd content
(Polish Academy of Sciences, 2008)
Three kinds of commercial Nd-Fe-B based materials were compared using 57Fe Mössbauer spectroscopy and X-ray analysis: near the Nd 2Fe14B stoichiometry and with both lowered and raised Nd content. Magnetically hard Nd2Fe14B ...
Synthesis, Characterization and Adsorptive Properties of Organobentonites
(Polish Acad Sciences Inst Physics, Warsaw, 2010)
In this paper partial and complete substitution of cations in the interlayer region of clay with different amounts of two aliphatic ammonium cations was performed with aim of synthesis of organobentonites with multipurpose ...
Polymer-Bonded Magnetic Materials with Various Nd-Fe-B Filler Content
(Polish Academy of Sciences, 2010)
One of the more important developments in magnetic materials, polymer bonded magnets, have opened a new world of application opportunities. The Nd-Fe-B/polymer composite materials offer an excellent combination of strong ...
Construction and Characterisation of Double Layer Capacitors
(Polish Academy of Sciences, 2010)
Electrochemical double-layer capacitor (also called supercapacitor) is an electrochemical energy storage device with a high power density, which could be used in application such as pulse power devices or electric vehicles. ...
