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 ...
Analyse of One Type of Resonant Cell
(9th International Conference on Telecommunications in Modern Satellite, Cable, and Broadcasting Serv, 2009)
Analyse of one type of resonant cell is proposed. One to three cells are combined into a low pass filter. The filter design curves for various substrates and cut off frequencies are presented.
New Modified Microstrip Bandstop Filter with Only One (First Order) Bandstop
(9th International Conference on Telecommunications in Modern Satellite, Cable, and Broadcasting Serv, 2009)
In this paper, a new structure with only one (first order) bandstop is reported. A simple trapezoid shape of the microstrip line is introduced instead of the more complicated pattern. It obtains simple simulation, optimization ...
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 ...
Wind turbine beyond 20 MW – Technology perspective
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije - SMEITS, Beograd, 2020)
The trend of wind turbine development has a special significance in the exploitation of renewable
energy sources. At higher altitudes, we have better wind energy utilization higher speed and
their conversion are achieved ...
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 ...
Adsorption-Desorption Noise in Plasmonic Chemical/Biological Sensors in Multiple Analyte Environment
(Smart Sensors, Actuators, and Mems Iv, 2009)
We analyzed the intrinsic noise of plasmonic sensors caused by the adsorption-desorption of gaseous analytes on the sensor surface. We analyzed a general situation when there is a larger number of different species in the ...
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 ...
