Dynamic and tunable chiral metamaterials with wideband constant chirality over a certain frequency band
(Elsevier GmbH, 2015)
We present numerically and experimentally a dynamic chiral metamaterial (MTM) that creates strong optical activity and circular dichroism. The proposed tunable structure has a very simple and more efficient configuration ...
Sensory applications of resonator based metamaterial absorber
(Elsevier GmbH, 2018)
Metamaterials are attractive media for scientific society for their potential multi-functional and a wide range of applications due to their unusual electromagnetic properties. In this paper, we present several important ...
Efficient AC-DC power factor corrected boost converter design for battery charger in electric vehicles

Investigation of cotton fabric composites as a natural radar-absorbing material
(Emerald Group Publishing Ltd., 2020)
Purpose The purpose of this paper is to investigate cotton fabric behavior that is exposed to radar waves between selected operation frequencies as an alternative radar-absorbing material (RAM) response. Cotton fabric ...
Improved Modeling of Microwave Structures Using Performance-Driven Fully-Connected Regression Surrogate
(Institute of Electrical and Electronics Engineers Inc., 2021)
Fast replacement models (or surrogates) have been widely applied in the recent years to accelerate simulation-driven design procedures in microwave engineering. The fundamental reason is a considerable-and often prohibitive-CPU ...
Hypersensitized Metamaterials Based on a Corona-Shaped Resonator for Efficient Detection of Glucose
(MDPI, 2021)
In this work, a new design for a real-time noninvasive metamaterial sensor, based on a corona-shaped resonator, is proposed. The sensor was designed numerically and fabricated experimentally in order to be utilized for ...
Microstrip leaky wave antenna for wide range of beam scanning in X band
