Printed Antenna Arrays with Cylindrical Parabolic Reflector
(20th Telecommunications Forum, TELFOR 2012 - Proceedings, 2012)
Concept of design and realization of high gain printed antenna structures is presented. They consist of antenna array, subreflector, feeding network and bal-un, all printed on the same dielectric substrate. Linear array ...
Vacuum Sensing Based on the Influence of Gas Pressure on Thermal Time Constant
(Institute of Electrical and Electronics Engineers Inc., 2014)
In this paper we propose a novel operating principle for thermal vacuum sensor. The sensor considered in this work consists of thermopiles and thermally isolating membrane structure. The operating principle of such sensor ...
Enhancing Performance of Nanohole-Based Plasmonic Sensors by Transparent Conductive Oxides
(Institute of Electrical and Electronics Engineers Inc., 2012)
We investigated a structure for surface plasmon-polariton-based chemical sensing consisting of a square 2D lattice of circular nanoapertures drilled in a plasmonic material on a dielectric substrate. Contrary to the usual ...
Bioremediation - innovative solutions for old environmental challenges
(Japan Society for Environmental Chemistry, 2018)
Until recently, we considered natural recycling capacities unlimited. However, industrial development, usage of fossil fuels and production of manmade compounds has led to the situation were the amount of generated waste ...
Petroleum pollution of alluvial sediments near Sava river, Serbia
(Society of Environmental Toxicology and Chemistry Europe, 2018)
The aim of our research was to determine the presence of petroleum pollutants and their vertical migration in the alluvial area of Sava river.
Permittivity Characterization Using a Double-Sided Parallel-Strip Line Resonator
(Institute of Electrical and Electronics Engineers Inc., 2018)
The paper introduces the new type of a microwave permittivity sensor with an open stub realized as a double-sided parallel-strip line without substrate. It can be totally immersed into the measured material and obtains ...
Composition and distribution of saturated hydrocarbons in the vicinity of heating plant in New Belgrade - alluvial sediments of the Sava River, Serbia
(Association of chemistry and environment, 2018)
The aim of our present research was to investigate the composition and distribution of saturated hydrocarbons in alluvial sediments of the Sava River in the vicinity of a heating plant in New Belgrade, Serbia.
Numerical Simulation of Transient Response of Chemical and Biological Micro/Nanofabricated Sensors Operating in Multianalyte Environments
(Institute of Electrical and Electronics Engineers Inc., 2014)
In different kinds of surface-based chemical and biological micro/nanosensors, interpretation of the experimentally obtained data is performed based on approximate solutions for the sensor response, valid for the case of ...
Applied atmogeochemical surveyed to identify areas of radon risk in rural areas of Serbia
(12th International Multidisciplinary Scientific GeoConference and EXPO - Modern Management of Mine P, 2012)
Selected locations of increased content of natural soil radionuclides are located in promising zone of internal Dinarides. The main characteristic of this zone is containing a numerous bauxite deposits, which appear in ...
Group-Delay-Controlled Multiple-Resonator-Based Harmonic Analysis
(Institute of Electrical and Electronics Engineers Inc., 2017)
In this paper, a modified and improved approach to the recently proposed multiple-resonator-based observer structure for harmonic estimation has been proposed. In the previous papers, two inherent particular cases have ...
