In this paper, a new multiband metamaterial absorber design is proposed and the numerical characterization is carried out. The design is composed of three layers with differently sized quadruplets in which the interaction among them causes the multiband absorption response in the infrared frequency regime. In order to characterize the absorber. and explain the multiband topology, some parametric studies with respect to the dimensions of the structure are carried out and the contributions of the quadruplets to the absorption spectrum are analyzed. According to the results, it is found that the proposed metamaterial absorber has five bands in the infrared frequency regime with the absorption levels of: 98.90%, 99.39%, 86.46%, 92.80% and 97.96%. Moreover, the polarization dependency of the structure is examined and it is found that the design operates well as a perfect absorber with polarization independency in the studied frequency range.

Dual-band high-frequency metamaterial absorber based on patch resonator for solar cell applications and its enhancement with graphene layers Ustunsoy, Mehmet Pasa; Sabah, Cumali (2016-12-05) In this paper, a dual-band high-frequency metamaterial absorber based on patch resonator is designed and analyzed for solar cells. In order to obtain a metamaterial absorber, metal-semiconductor-metal layers are combined. The results of the designed structure are shown in the infrared and visible ranges of solar spectrum. Structural parameters and dimensions of the device have a significant importance on the performance of the designed absorber. The simulations are carried out with full-wave electromagnetic...
Multi-Band Metamaterial Absorber: Design, Experiment and Physical Interpretation Dincer, F.; KARAASLAN, MUHARREM; ÜNAL, EKİN ANIL; Akgol, O.; Sabah, C. (2014-03-01) This paper presents the design, fabrication, characterization and experimental verification of a perfect Multi-Band Metamaterial (MTM) absorber (MA) based on a simple configuration of a rectangular resonator and strips operating in microwave frequency regime. The proposed multi-band MA provides perfect absorption with TE-incident angle independency. Maximum absorption rate is achieved as 99.43% at 5.19 GHz for simulation and 98.67% at 5.19 GHz for experiment, respectively. The measurement results of the fab...
Multiband Metamaterial Absorber Design Based on Plasmonic Resonances for Solar Energy Harvesting Mulla, Batuhan; Sabah, Cumali (2016-10-01) A new metamaterial absorber is designed and characterized numerically for the harvesting of solar energy. The design is composed of three layers in which the interaction among them gives rise to the plasmonic resonances. The main operation frequency range of the proposed structure is chosen to be the visible regime. However, the design is also analyzed for the infrared and ultraviolet regimes. In order to characterize the absorber, some parametric studies with respect to the dimensions of the structure are ...
Cold Test Validation of Metamaterial Based Rectangular Slow Wave Structure for High-Power Backward-Wave Oscillators Eser, Dogancan; Demir, Şimşek (2019-06-01) In this paper, a novel S band metamaterial based rectangular slow-wave structure (RSWS) is proposed for high-power backward-wave oscillator (BWO). The circular waveguide is loaded with R-SWS that shows negative permittivity and permeability. Since RSWS shows negative permittivity and permeability which is the key characteristics of metamaterial, it can operate below the cut-off frequency. CST Studio Suite is used to analyze high frequency characteristic of SWS. Dispersion diagram of the unit cell is observe...
Optimization of Power Conversion Efficiency in Threshold Self-Compensated UHF Rectifiers With Charge Conservation Principle Gharehbaghi, Kaveh; KOÇER, FATİH; Külah, Haluk (2017-09-01) This paper presents a compact model for threshold self-compensated rectifiers that can be used to optimize circuit parameters early in the design phase instead of time-consuming transient simulations. A design procedure is presented for finding the optimum aspect ratio of transistors used in the converter and number of rectifying stages to achieve the maximum power conversion efficiency. In the presented analysis, the relation between the power conversion efficiency and the load current over the variation o...
