Diffraction of waves by a boundary between two half-planes with different resistivities.

Abstract

The solution of the diffraction problem of waves by a junction between two resistive half-screens is obtained by using the wedge diffraction field expression, introduced by Maliuzhinets [Ann. Phys.461, 107 (1960)]. The two half-planes, located at the same coordinate plane, have different surface resistivities. The new field expression is compared with the solution of Senior ["Diffraction by a material junction," http://deepblue.lib.umich.edu/handle/2027.42/21043] for the scattered waves. The important aspects of the approach are discussed in the light of the numerical results.
