Diffracted Fields by the Edge of Wedge and Reflected Fields from Surface of Wedge

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 works, we have shown that the shape and material of wedges do not affect the diffracted fields. In this paper, we analyze the reflected and diffracted fields by one or two wedges and compare the effects that wedge shapes and materials give to the reflected and diffracted fields for horizontal and vertical polarized incidence. The numerical calculations are carried out for one and two wedges, which are composed by various inner angles and different materials. We also discuss about the diffracted fields close to the wedge surface. The numerical results show that for one or two wedges, wedge shapes, materials and incident polarization don´t give significant effect to diffracted fields, but the waves incident close to the wedge surfaces are affected by them.
