Analysis of light scattering of a Gaussian beam by a perfect electromagnetic conductor (PEMC) sphere

Electromagnetic scattering by a sphere is one of the most significant problem in electromagnetics as reported by the optical research community. Based on the framework of generalized Lorenz–Mie theory (GLMT), we investigated the scattering of a Gaussian Beam (a strongly focused basic TEM00\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\text{TEM}}_{00}$$\end{document} mode laser beam) by a perfect electromagnetic conductor sphere. The influence of parameters i.e., sphere size parameter, beam waist radius, and beam center coordinate position on the scattering and extinction efficiencies, normalized energy flow, and scattering asymmetry factor is numerically analyzed. On varying the prior mentioned factors, the amplitude of efficiency factors is considerably modified. By increasing the waist radius, the normalized energy flow increases for the PEMC sphere. The investigation of the scattering characteristics for PEMC sphere illuminated by a Gaussian beam can also be extended to study the metamaterial structures.
