ABSTRACT
In this article, a novel binary Wind Driven Optimization (WDO) algorithm is presented for the synthesis of six-band Metamaterial Absorber (MA). Synthesis of the unit cell structure of MA is done by optimizing the presence of each unit pixel of pixelated Frequency Selective Surface (FSS). Numerical simulation of this optimized absorber shows six discrete bands of absorptions at 7.6, 10.1, 13.3, 14.7, 15.8 and 16.7 GHz with more than 90% absorptivity under normal incidence of the wave. The proposed absorber is ultra-thin, polarization insensitive and has good performance over a wide angle of incidence. The numerical simulation and experimental results are in close agreement.
