Scattering of Waves by a Planar Junction Between Resistive Half-Screen and Perfectly Electric Conducting Wedge

Abstract

The diffraction of plane waves by a planar junction between a resistive half-plane and perfectly conducting wedge is investigated. First of all, the relation between the scattered geometrical optics waves and diffracted fields by a wedge is outlined. Then the scattered GO fields of the planar junction are obtained by subtracting the initial fields from the total geometrical optics waves. The diffracted waves by the junction is derived with the aid of the scattered GO waves' structure. The behaviour of the fields is analysed numerically.
