Abstract
En 中文
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., \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\:{\varvec{\epsilon\:}}_{\varvec{e}\varvec{f}\varvec{f}}$$\end{document} & \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\:{\varvec{\mu\:}}_{\varvec{e}\varvec{f}\varvec{f}}$$\end{document}, whereas the second technique is explained using current distribution. The structure is mounted on dielectric substrate (FR-4). The mounted structure is tested and measured inside the anechoic chamber. The measured result obtained from the chamber are in close agreement with the simulated one which slightly differs due to fabrication tolerance. At last, the presented MCP structure is compared with the past articles and listed in the form of a table.
