Abstract

Estimation of the scattering of electromagnetic waves by buildings and other obstacles is very important for wireless communications. In our previous work, we have examined the diffracted fields by two horizontal edges which make an arbitrary angle. In this paper, we compare the diffracted fields between parallel edges and edges with arbitrary angle. The numerical calculation results show that when the angle between two edges increases, relatively strong orthogonal polarized wave components appear, but the principal components are almost the same as the incident wave.
