Title: A Spectral Iterative Approach for Analyzing the Scattering of Cylindrical Waves from One Dimensional Wire Gratings
Authors: Dire, James R.
Committee Members: Noon, Jack H.
Summary: The scattering of cylindrical waves, infinite in the axial direction, from a one dimensional infinite, planar, periodic array of wires is investigated. The cylindrical wavefront is divided into planar segments. Each planar segment is treated individually as an infinite plane wave incident upon the periodic structure. The reflection characteristics of each plane wave is determined by analyzing the electromagnetic scattered fields using the secant method to solve an iterative algorithm. The derivation of the method as applied to surfaces containing a one dimensional parallel thin wire grating is presented. The reflection coefficients for cylindrical waves are determined by combining the reflection coefficients of the planar segments. The reflection characteristics of the grating as a function of wire spacing, wire thickness and polarization of the incident field are calculated.
