A Double-Layer Metamaterial-Based Technique for Interference Mitigation and Shielding of Planar Microwave Structures

Papadimopoulos, Athanasios; Karamanos, Theodosios; Tsitsas, Nikolaos; Valagiannopoulos, Constantinos; Kantartzis, Nikolaos; Tsiboukis, Theodoros (2016-07)

An efficient cloaking-shielding technique based on the use of a double superstrate-layer overlay is developed in this paper for planar microstrips. The metamaterial-inspired formulation reduces considerably the induced ...
Conjugately-Matched Uniaxial Metamaterials Make Extremely Efficient Absorbers, Emitters, and Reflectors

Valagiannopoulos, Constantinos; Simovski, C. R.; Tretyakov, Sergei A. (2016-09)

The speed with which electromagnetic energy can be wirelessly transferred from a source to the user is a crucial parameter for performance of a large number of electronic and photonic devices. In this presentation we ...
On Self-Oscillating Wireless Power Transfer

Tretyakov, Sergei; Ra’di, Younes; Simovski, Constantin; Valagiannopoulos, Constantinos (IEEE International Conference on Microwaves, Antennas, Communications and Electronic Systems (COMCAS), 2017-11-13)

Abstract—Conventional wireless power transfer systems consist of a microwave power generator located at one place and a microwave power receiver located at a distance. To realize efficient power transfer, the system ...
Random Number Hardware Generator Using Geiger-Mode Avalanche Photo Detector

Beznosko, Dmitriy; Beremkulov, T.; Duspayev, A.; Iakovlev, A. (2015)

The main problems with existing hardware random number generators today are either low speed and/or prohibitively high cost. The physical concept and test results of sample data of the high-speed hardware true random number ...
The distributed particle detectors and data acquisition modules for Extensive Air Shower measurements at "HT-KZ" experiment

Duspayev, A.; Batyrkhanov, A.; Beremkulov, T.; Beznosko, Dmitriy; Iakovlev, A.; Yessenov, M.; Beisembaev, R. U.; Zhukov, V. V. (2015)

"HorizonT-Kazakhstan" (HT-KZ) is an extensive air shower new detector system of a new type to be constructed at Nazarbayev University (NU), Astana, KZ. It is based on the idea of a previous generation detector that is ...
