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 according to the dimension and geometry variations. For the harvesting application, three different efficiencies are suggested, discussed, and calculated in terms of their contribution to the conditional realization of the connection between the absorption characteristics of the material and its energy harvesting functionality. Also the multi-band absorption characteristics of no-load conditions are presented and compared with the loading conditions through the energy harvesting. As a result, 50 % of the incoming wave energy whose correspondence is 0.25 W is converted to real power through the resistive loads at 5.88 GHz.

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 metamaterial absorber based on circle-shaped resonators with interference theory
Dincer, Furkan; Karaaslan, Muharrrem; AKGÖL, OĞUZHAN; ÜNAL, EMİN; Sabah, Cumali (2015-11-10)
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 ab...
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...
Extremely-broad band metamaterial absorber for solar energy harvesting based on star shaped resonator
BAĞMANCI, MEHMET; KARAASLAN, MUHARREM; ÜNAL, EMİN; AKGÖL, OĞUZHAN; Sabah, Cumali (2017-07-01)
A new metamaterial absorber (MA) is investigated and shown numerically for solar energy harvesting for future solar cell applications. The structure consists of two metals and one dielectric layer having different thicknesses. Owing to this combination, the structure exhibits plasmonic resonance characteristics. In the entire spectrum of visible frequency region, the obtained results show that investigated structure has perfect absorptivity which is above 91.8%. Proposed structure also has 99.87% absorption...
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...
