Implementation of a perfect metamaterial absorber into multi-functional sensor applications

Sabah, C.
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 sensor achieves good sensing capabilities for both applications. The proposed perfect MA -based sensor variations enable many potential applications in medical or food technologies.

Bakir, Mehmet; KARAASLAN, MUHARREM; Dincer, Furkan; DELİHACIOĞLU, KEMAL; Sabah, Cumali (2015-09-01)
An electromagnetic (EM) energy harvesting application based on metamaterials is introduced. This application is operating at the the industrial, scientific, and medical band (2.40 GHz), which is especially chosen because of its wide usage area. A square ring resonator (SRR) which has two gaps and two resistors across the gaps on it is used. Chip resistors are used to deliver the power to any active component that requires power. Transmission and reflection characteristics of the metamaterial absorber for en...
Investigation of microwave metamaterial based on H-shaped resonator in a waveguide configuration and its sensor and absorber applications
Sabah, Cumali; Taygur, Mehmet Mert; ZORAL, EMİNE YEŞİM (2015-04-13)
A microwave metamaterial (MTM) based on H-shaped resonator in a waveguide configuration is introduced and investigated both numerically and experimentally for X-band frequencies. The proposed model is designed and fabricated on both sides of the substrate and exhibits strong magnetic resonance at around 10.5GHz. Additionally, it has very simple design which improves and simplifies the fabrication process. Besides, only one single slab is used in the simulation and experiment which provides a reduction in th...

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...
Sensitive Metamaterial Sensor for Distinction of Authentic and Inauthentic Fuel Samples
Tumkaya, Mehmet Ali; Dincer, Furkan; KARAASLAN, MUHARREM; Sabah, Cumali (2017-08-01)
A metamaterial-based sensor has been realized to distinguish authentic and inauthentic fuel samples in the microwave frequency regime. Unlike the many studies in literature on metamaterial-based sensor applications, this study focuses on a compact metamaterial-based sensor operating in the X-band frequency range. Firstly, electromagnetic properties of authentic and inauthentic fuel samples were obtained experimentally in a laboratory environment. Secondly, these experimental results were used to design and ...
