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 fabricated prototype are in a good agreement with the numerical results. Furthermore, we introduce a numerical analysis in order to show physical interpretation of the MA mechanism in detail. Additionally, a sensor application of the proposed multi-band MA is presented to demonstrate an extra feature of the suggested structure. As a result, the proposed multi-band MA enables myriad potential application areas such as radar, stealth, shielding, communication, imaging and medical applications.

Diamond-shaped hole array in double-layer metal sheets for negative index of refraction
Yilmaz, A.; Sabah, C. (2013-03-01)
In this paper, a new design of hole array in a double-layer periodic arrangement is introduced and investigated both numerically and experimentally for the negative index of refraction. The structure shows similar behavior to that of the corresponding fishnet metamaterials. The effective constitutive parameters are revealed by using retrieval procedure to verify the negative refraction nature of the proposed structure. A relatively high figure of merit (FOM=Re(n)/Im(n)=70.05) is achieved at the K-band (1826...
