Evaluation of a Method for Finding Diffraction Points on Two Edges with Arbitrary Angle and Its Diffracted Fields

Estimation of the scattering of electromagnetic waves by buildings and other obstacles is very important for wireless communications in urban area. In our previous work, we have examined the diffracted fields by two horizontal edges with an arbitrary angle. In this paper, we consider the diffracted fields by two edges with an arbitrary angle which change in both horizontal and vertical directions. The numerical evaluation are carried out for two wedges and we compare the diffracted fields between parallel and arbitrary angle of edges. The 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, and the effect of edge slant in vertical direction is smaller than horizontal one.
