Investigation of diffracted fields in buildings and wedges: a comparison study

In order to have an effective utilisation 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 except the diffracted fields close to wedge surfaces. In this paper, we compare the diffracted fields of the wedges whose inner angles are 0 and a building for examining the fields close to wedge surface. The numerical calculations were carried out for two wedges, a conducting building and a concrete building. We discuss diffracted fields by two wedges and a building for the case when a horizontal or vertical polarised wave is perpendicularly or obliquely incident to the edges.
