The synthesis of pixelated metamaterial cross polarizer using binary wind driven optimization algorithm

In this paper synthesis of two wideband Metamaterial Cross Polarizer (MCPs) is proposed. The synthesis of proposed MCPs is done by using Binary Wind Driven Optimization (BWDO) techniques which is an advance version of Wind Driven Optimization (WDO) techniques. Maximum number of iterations is done to achieve the desired wideband responses. Model-I is obtained after ten iterations which achieve − 10 dB PCR bandwidth of 5.09 GHz ranging from 6.59 to 13.70 GHz with three PCR peak at 7.6, 9.8 and 11.9 GHz with percentage PCR of 99.89, 99.90 and 99.02% respectively. Similarly, Model-II is obtained after 18 iterations which achieved − 10 dB PCR bandwidth of 5.67 GHz ranging from 5.96 to 12.80 GHz with three PCR peak at 6.8, 8.5 and 11.9 GHz with percentage PCR of 99.85, 99.88 and 99.29% respectively. The wideband cross polarization mechanism is explained by the analysis of wideband MCPs with two different techniques: first, with the help of effective Electromagnetic (EM) parameters ε _eff and μ _eff and secondly with the help of current distribution techniques. The proposed MCPs is fabricated on FR-4 substrate and tested inside the Anaerobic Chamber. The tested and simulated results obtained are very close to each other with little bit of variance with respect to fabrication tolerance. At last, the proposed MCPs are compared with the already reported MCPs.
