Diffraction of a plane electromagnetic wave by a circular dielectric cylinder with a finite-length perfectly conducting metal strip on the Cylinder’s lateral surface

Abstract

The diffraction of E-and H-polarized plane electromagnetic waves by a circular dielectric cylinder with a finite-length perfectly conducting metal strip on the cylinder’s lateral surface is considered. The diffraction problem is solved with the use of the method of singular integral equations. The distributions of the surface current on the metal strip are calculated. The patterns of the reflected electromagnetic field are determined from these distributions for various incidence angles of the plane electromagnetic wave. It is shown that the pattern of the diffracted field strongly depends on the angle of the wave incidence on the metal strip.
