Transverse magnetic scattering of two incident plane waves by a dielectric coated cylindrical reflector

Abstract

Scattering characteristics of two plane waves are investigated for a circular cylinder covered by a dielectric substance. Fields are assumed to be transverse magnetic (TM) and represented in an exponential series form. The diffracted radiations are found by applying the boundary conditions to the wave functions. The wave transformation method and the orthogonality of the exponential functions are respectively employed to obtain an infinite series in the solution. Numerical results are evaluated by reducing the infinite series to a finite number of terms and comparing estimates with the single plane wave scattering situation.

Directive Em Radiation of a Line Source in the Presence of a Coated Pemc Circular Cylinder

“…Electromagnetic scattering by coated circular cylinders is a classical problem in electromagnetics and has been investigated by several researchers [17][18][19][20][21][22][23][24][25][26][27][28]. Scattering behavior becomes much more complicated if scattering obstacle is made of layers or sections of several materials.…”

Electromagnetic Scattering of Two or More Incident Plane Waves by a Perfect Electromagnetic Conductor Cylinder Coated With a Metamaterial

“…It is obvious that PMC corresponds to M = 0, while PEC corresponds to M = ±∞. Scattering of electromagnetic waves from coated cylinder, has been extensively studied [20][21][22][23][24][25][26][27]. Metamaterial with both negative permittivity and permeability is known as backward (BW) medium or double negative (DNG) medium.…”
