This study presents design, fabrication, and measurement of a metamaterial absorber (MA) based on discontinuous cross-wire-strip (CWS) resonators. This suggested that MA has a simple geometry configuration and introduces perfect absorption approximately 99.79% at 3.42 GHz for simulation and 99.72% at 3.44 GHz for experiment. In addition, the designed model can be used to realize the broadband absorber for desired frequency ranges. Besides, numerical simulations validate that the MA could achieve very high absorptions at wide angles of incidence for both transverse electric and transverse magnetic waves. The experimental results are in good agreement with the numerical simulations. Moreover, this study presents a numerical analysis in order to explain physical interpretation of MA mechanisms in detail. The proposed model and its variations enable myriad potential applications such as stealth and radar technologies.

Polarization-insensitive FSS-based perfect metamaterial absorbers for GHz and THz frequencies Sabah, Cumali; Dincer, Furkan; KARAASLAN, MUHARREM; ÜNAL, EMİN; Akgol, Oguzhan (American Geophysical Union (AGU), 2014-04-01) New perfect frequency selective surface (FSS) metamaterial absorbers (MAs) based on resonator with dielectric configuration are numerically presented and investigated for both microwave and terahertz frequency ranges. Also, to verify the behaviors of the FSS MAs, one of the MAs is experimentally analyzed and tested in the microwave frequency range. Suggested FSS MAs have simple configuration which introduces flexibility to adjust their FSS metamaterial properties and to rescale the structure easily for any ...
Forward and reverse bias current-voltage characteristics of Au/n-Si Schottky barrier diodes with and without SnO2 insulator layer GÖKÇEN, MUHARREM; ALTINDAL, ŞEMSETTİN; Karaman, M.; Aydemir, U. (Elsevier BV, 2011-11-01) The effects of interfacial insulator layer, interface states (N-ss) and series resistance (R-s) on the electrical characteristics of Au/n-Si structures have been investigated using forward and reverse bias current-voltage (I-V) characteristics at room temperature. Therefore, Au/n-Si Schottky barrier diodes (SBDs) were fabricated as SBDs with and without insulator SnO2 layer to explain the effect of insulator layer on main electrical parameters. The values of ideality factor (n), R-s and barrier height (Phi(...
Polarization Angle Independent Perfect Metamaterial Absorbers for Solar Cell Applications in the Microwave, Infrared, and Visible Regime Dincer, Furkan; Akgol, Oguzhan; KARAASLAN, MUHARREM; ÜNAL, EMİN; Sabah, Cumali (EMW Publishing, 2014-01-01) We design, characterize, and analyze a new kind of metamaterial (MTM) absorber (MA) in different frequency regions for the solar cell applications. This MTM based structure is particularly presented in a range of the solar spectrum in order to utilize the solar energy effectively. The proposed MTM based solar cell provides perfect absorption for both infrared and visible frequency ranges and can be used for the realization of more efficient new solar cells. The structure is also tested in terms of the polar...
Electromagnetic optimization of corrugated metallic sheets for maximum power focusing Altinoklu, Askin; Karaosmanoglu, Bariscan; Ergül, Özgür Salih (Informa UK Limited, 2017-01-01) We present full-wave electromagnetic optimization of corrugated metallic sheets to achieve maximum power focusing at desired locations when illuminated by plane waves. The corrugations are freely applied by moving the discretization nodes, leading to huge optimization spaces that are scanned by employing genetic algorithms. The required simulations are performed accurately and efficiently via the method of moments or the multilevel fast multipole algorithm. Hundreds of thousands of simulations are performed...
Trapping center parameters of TlGaSe2 layered crystals Yuksek, NS; Kavas, H; Hasanlı, Nızamı; Ozkan, H (Elsevier BV, 2004-02-15) Thermally stimulated current measurements are carried out on as-grown TlGaSe2 layered single crystals in the temperature range of 90-220 K with various heating rates. Experimental evidence is found for the presence of two trapping centers with activation energy 98 and 130 meV. The retrapping process is negligible for these levels, as confirmed by good agreement between the experimental results and theoretical predictions of the model that assumes slow retrapping. The calculation yielded 2.3 x 10(-24) and 1....
