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 (EM) solver based on the finite integration technique. In the first simulation, the constitutive parameters of the structure are selected as constant in which the metamaterial absorber has 99.99% absorption at 558.75 THz and 99% absorption at 216.75 THz. When the structure parameters are designed again according to Drude model, the second simulation results show that the metamaterial absorber has 99.96% absorption at 514.5 THz and 99.63% absorption at 197.25 THz. Moreover, the second simulation results show that the proposed design is also polarization and incident angle insensitive. Furthermore, the structure is enhanced by the integration of the graphene layer(s). In addition, the fractional bandwidths (FBW) for the resonances are also calculated to show the quality of the absorber. As a result, the proposed metamaterial absorber based on patch resonator and its enhancement with graphene present high absorption in the infrared and visible ranges and can be used in many meta material and solar applications.

Thin film (6,5) semiconducting single-walled carbon nanotube metamaterial absorber for photovoltaic applications Obaidullah, Madina; Esat, Volkan; Sabah, Cumali (2017-12-01) A wide-band (6,5) single-walled carbon nanotube metamaterial absorber design with near unity absorption in the visible and ultraviolet frequency regions for solar cell applications is proposed. The frequency response of the proposed design provides wide-band with a maximum of 99.2% absorption. The proposed design is also simulated with (5,4), (6,4), (7,5), (9,4), and (10,3) chiralities, and results are compared to show that the proposed design works best with (6,5) carbon nanotube (CNT) but also good for ot...
Theoretical and thermal characterization of a wideband perfect absorber for application in solar cells Rufangura, Patrick; Sabah, Cumali (2016-12-01) This paper suggests a metamaterial (MTM) absorber structure to be used for efficiency improved solar cell. The proposed MTM absorber consists of the topmost three concentric circular ring resonators, and a ground metal plane sandwiched to the top layer with a dielectric spacer. Numerical simulation and theoretical (interference theory) studies on the proposed design show a wideband with near-perfect (>99%) absorption response in the visible frequency region of the solar spectrum. Thermal characterization of...
Implementation of a perfect metamaterial absorber into multi-functional sensor applications AKGÖL, OĞUZHAN; KARAASLAN, MUHARREM; ÜNAL, EMİN; Sabah, C. (2017-05-30) Perfect metamaterial absorber (MA)-based sensor applications are presented and investigated tigated in the microwave frequency range. It is also experimentally analyzed and tested to verify the behavior of the MA. Suggested perfect MA -based sensor has a simple configuration which introduces flexibility to sense the dielectric properties of a material and the pressure of the medium. The investigated applications include pressure and density sensing. Besides, numerical simulations verify that the suggested s...
Electromagnetic Energy Harvesting By Using Tunable Metamaterial Absorbers Bakir, Mehmet; KARAASLAN, MUHARREM; Dincer, Furkan; Akgol, Oguzhan; ÜNAL, EMİN; DELİHACIOĞLU, KEMAL; Sabah, Cumali (2015-05-19) In this study, electromagnetic (EM) energy harvesting by using metamaterial absorber is numerically explained. Operation frequency is 2.40 GHz since it is the industrical scientific and medical (ISM) band. This band is especially chosen due to most of the customer electronic devices are working in this band. Split ring resonator that have two splits on it used in this study, chip resistors are placed on these splits for wireless energy transfer to the devices. 83.6% efficient electromagnetic energy harvesti...
Improvement of multiband absorption with different technics (graphene, ito, and hole) for metamaterial absorber at optical frequencies Mulla, Batuhan; Sabah, Cumali (2018-10-01) Three absorption improvement techniques are numerically applied to a multiband metamaterial absorber design for solar energy harvesting. These techniques are the following: the reshaping of the back metallic plate, the integrating of graphene sheets, and the utilizing of indium tin oxide (ITO), in the design. Based on numerical simulation results, each of these methods has the capacity to enhance total absorption rates. In addition to the enhancement in the total absorption rates, new absorption peaks are a...
