Binary wind driven optimization techniques for Metamaterial Cross Polarizer
摘要
This article presents synthesized Metamaterial Cross Polarizer (MCP) using Binary Wind Driven Optimization (BWDO) technique. BWDO is an advance version of WDO techniques. To achieve wideband response uttermost number of iterations is done at the time of synthesis. The wideband responses below − 10 dB is considered as a bandwidth and its ranges from 7.56 to 11.94 GHz. To achieve best response 50 number of iterations has to be performed. The Polarization Conversion Ratio (PCR) is considered at three distinct peaks i.e., at 8.3, 10.6 and 11.9 GHz with 99.87, 98.93 and 96.71% respectively. For explaining polarization conversion mechanism two different techniques is discussed in this article. The first technique is explained using the effective Electromagnetic (EM) parameters, i.e.,
