Abstract: Tunable and multi-band metamaterial (MTM) based perfect microwave
absorber (MA) is designed, implemented, and characterized. Firstly, dual-band
MA with has two distinct resonances is investigated both numerically and
experimentally which is also tested according the incident angle and
polarization independencies. Then, the modified versions of MA are investigated
and compared with respect to their absorbance, mechanical tunability, and
multi-band characters. As a result, the suggested MAs with perfect absorption
(including incident angle and polarization independencies) display good
performance among their counterparts and can be used in myriad potential
applications such as high frequency and sensor applications which are also
presented.
