Electromagnetic Fields Diffracted by Two Horizontal Edges with Arbitrary Angle Considering Different Heights

In order to have an effective utilization of the radio wave resources, it is important to estimate propagation path in the urban area. In our previous work, we have examined the diffracted fields by two edges with an arbitrary angle in a plane. In this paper, the diffracted fields by two edges which are in different heights and make an arbitrary angle are analyzed. The numerical calculation is carried out on perfect conductor, concrete and earth wedges. The results show that when the angle between two edges increases, relatively strong orthogonal polarized wave components appear to the incident wave.
