A Method for Finding Diffraction Points on Two Edges with Arbitrary Angle and Its Diffracted Fields

Abstract

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 calculations are carried out for two edges. The results show that when the angle between two edges increases, relatively strong orthogonal polarized wave components appear to the incident wave.
