We theoretically and numerically designed a perfect metamaterial absorber at microwave frequencies. The proposed design has a very simple geometry, wide band properties and provides perfect absorption for all polarization angles which is one of the most desired properties for an absorber structure to be used in the applications where the source polarization is unknown. In order to explain the absorption mechanism both numerical and theoretical analyses are carried out. Designed structure offers a perfect absorption at around 9.8 GHz. The resonance frequency does not change depending on the source wave polarization. In addition, it can be easily reconfigured for THz and infrared regimes for different applications such as sensors, defense systems and stealth technologies.

Polarization independent triple-band (5,4) semiconducting carbon nanotube metamaterial absorber design for visible and ultraviolet regions Obaidullah, Madina; Esat, Volkan; Sabah, Cumali (2017-10-01) Various metamaterial absorber designs operating in the microwave, infrared, visible, and ultraviolet frequency regions have been proposed in the literature. However, only a few studies have been done on the metamaterials that absorb in both visible and ultraviolet solar spectra. A triple-band polarization-insensitive metamaterial absorber structure with semiconducting single-walled carbon nanotube as the dielectric layer is proposed to efficiently absorb the incident electromagnetic radiations in visible an...
Polarization angle independent perfect multiband metamaterial absorber and energy harvesting application Gunduz, O. T.; Sabah, C. (2016-03-01) A new kind of multi-band metamaterial absorber based on the concentric ring resonators is engineered to be used in various microwave applications including energy harvesting. Numerical investigations are carried out step by step for observation of the effect of each ring resonator. The results reveal that the structure almost perfectly absorbs the electromagnetic wave with polarization angle independency at multiple resonant frequencies in the microwave range. Additionally, the structure is characterized ac...
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 ...
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...
Polarization and angle independent perfect metamaterial absorber based on discontinuous cross-wire-strips Dincer, Furkan; KARAASLAN, MUHARREM; ÜNAL, EMİN; Akgol, Oguzhan; Demirel, Ekrem; Sabah, Cumali (Informa UK Limited, 2014-04-13) 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 a...
