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 polarization angle independency. The suggested MA has a simple configuration which introduces flexibility to adjust its MTM properties to be used in solar cells and can easily be re-scaled for other frequency ranges. Our experimental results in microwave frequencies confirm the perfect absorption for the resonance frequency and agree with the simulation results. This means that the developed MA for solar cells will offer perfect absorption in infrared and even in visible frequencies.

Polarization angle insensitive dual-band perfect metamaterial absorber for solar cell applications Rufangura, Patrick; Sabah, Cumali (2015-04-29) A metamaterial absorber that effectively harvests solar energy is being proposed in this paper using a simple and high flexible structure. The proposed structure unit cell comprises of three vital layers. The ground metallic plane, an intermediate dielectric spacer while patches are wisely prepared on the top of a dielectric spacer. Geometrical parameters of the proposed metamaterial is studied in order to get insight on their impact for the absorption behaviour of the structure. The results from simulation...
Polarisation insensitive tunable metamaterial perfect absorber for solar cells applications Rufangura, Patrick; Sabah, Cumali (Institution of Engineering and Technology (IET), 2016-12-01) Developing a perfect absorber based on metamaterials (MTMs) is a promising technique towards improving the efficiency of solar photovoltaic cells. In this study, a novel MTM-based perfect absorber (MPA) is proposed for solar cell applications, which exhibits an excellent single-band with high absorption rate of 99.7% in visible frequency regime (resonance frequency of 614.4 THz) with an outstanding absorption bandwidth of 15.5%. The proposed design presents a high symmetry flexibility which makes it easy to...
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 ...
Mutual coupling of printed elements on a cylindrically layered structure using closed-form Green's functions Acar, R. C.; Dural, G. (EMW Publishing, 2008-01-01) A hybrid method to calculate mutual coupling of electric or magnetic current elements on a cylindrically layered structure using closed-form Green's functions is presented. When rho = rho' and phi is not very close to phi', closed-form Green's functions are employed in the calculation of MoM matrix entries. When both rho = rho' and phi = phi', series representation of the spectral domain Green's functions do not converge, therefore closed-form Green's functions can not be employed. In that case MoM matrix e...
A monolithic phased array using 3-bit distributed RF MEMS phase shifters Topalli, Kagan; Aydın Çivi, Hatice Özlem; Demir, Şimşek; Koç, Seyit Sencer; Akın, Tayfun (Institute of Electrical and Electronics Engineers (IEEE), 2008-02-01) This paper presents a novel electronically scanning phased-array antenna with 128 switches monolithically implemented using RF microelectromechanical systems (MEMS) technology. The structure, which is designed at 15 GHz, consists of four linearly placed microstrip patch antennas, 3-bit distributed RF MEMS low-loss phase shifters, and a corporate feed network. MEMS switches and high-Q metal-air-metal capacitors are employed as loading elements in the phase shifter. The system is fabricated monolithically usi...
