Calculation of Reflected EM Fields by Mixed Plane Dielectric Media Using Green's Functions for Applications in Urban Environment

Abstract : Green's functions for semi-infinite media are derived and used to calculate the reflected electromagnetic fields by plane composite dielectric surfaces. The method is not demanding in terms of computer resources and calculation time; it is thus applied to exterior building facades in urban environments. The method takes into account the architectural details which are usually neglected in ray-tracing algorithms.
