Microwave energy harvesting based on metamaterial absorbers with multi layered square split rings for wireless communications
(Elsevier, 2017)
We propose the design of a multiband absorber based on multi-layered square split ring (MSSR) structure. The multi-layered metamaterial structure is designed to be used in the frequency bands such as WIMAX, WLAN and satellite ...
Implementation of a perfect metamaterial absorber into multi-functional sensor applications
(World Scientific Publishing Co. Pte Ltd., 2017)
Perfect metamaterial absorber (MA)-based sensor applications are presented and investigated tigated in the microwave frequency range. It is also experimentally analyzed and tested to verify the behavior of the MA. Suggested ...
Fraktal anten parametrelerinin metamalzemeler yardımıyla iyileştirilmesi
(İskenderun Teknik Üniversitesi / Mühendislik ve Fen Bilimleri Enstitüsü / Elektrik-Elektronik Mühendisliği Anabilim Dalı, 2019)
Metamalzemeler (MTM) doğada bulunmayan, yapay olarak istenilen amaca uygun bir şekilde tasarlanan ve üretilebilen malzemelerdir. Son yıllarda, gizleme (Shelby, Smith, & Schultz, 2001), süper lensler (Pendry, Schurig, & ...
C-shaped split ring resonator type metamaterial antenna design using neural network
(SPIE, 2021)
A C-shaped split ring resonator-based metamaterial (MTM) structure placed on a patch antenna is proposed. An artificial neural network (ANN) is applied to design and determine dimensions of an MTM structure that is similar ...
Chiral metamaterial-based sensor applications to determine quality of car lubrication oil
(SAGE Publications, 2021)
Motor oils have to be changed periodically in a period of 10.000-20.000 km according to the motor types. A chiral metamaterial sensor that operates in X band is developed to determine the quality of motor oils, numerically ...
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 ...
Seismic metamaterials for low-frequency mechanical wave attenuation
(Springer, 2021)
In this study, a triangular array of cylindrical holes was shown to function as a local resonator to seismic metamaterials against the vibration generator loading in the geophysics concept. The field test showed that the ...
Optimizing the Gain and Directivity of a Microstrip Antenna with Metamaterial Structures by Using Artificial Neural Network Approach
(Springer, 2021)
The purpose of this study is to improve the gain and directivity of the microstrip patch antenna by means of metamaterial (MTM) structures. As it is known, antennas have power densities in a certain direction, and the ...
Monopole antenna integrated cavity resonator for microwave imaging
(SPIE, 2021)
We present a system that displays an image of any metal structure in a scene by the use of microwave radiation from a cavity resonator in a 10-GHz frequency band. An 80 mm x 80 mm mushroom-like electromagnetic band gap ...
Wideband Microwave Absorber Comprising Metallic Split-Ring Resonators Surrounded With E-Shaped Fractal Metamaterial
(Institute of Electrical and Electronics Engineers Inc., 2021)
A specially designed metallic E-shaped fractal-based perfect metamaterial absorber (PMA) with fairly wideband absorptivity in the K- and Ka-bands of the microwave regime was investigated. The PMA top surface is comprised ...
