Plane wave scattering by a thick lossy dielectric half-plane

A solution is obtained for the scattering of a plane wave by a lossy, thick, dielectric half-plane, with a view to applications for calculating the TV electromagnetic wave scattering by a tall building made of concrete. The problem is analytically framed in terms of the incident and scattered electric fields, assuming the polarization in each case to be invariant. Boundary conditions are defined within which Fourier components of the scattered field are calculated. The far-fields were analyzed employing the saddle-point method. Numerical examples for 100 MHz broadcasts are presented, demonstrating a good agreement in the illuminated region between calculations for a lossy dielectric and a perfectly conducting half plane.
