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 this paper, the characteristics of the diffracted fieldsby two horizontal edges of a building rooftop are discussed for two cases: a building without or with parapets...
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 which are in different and same heights. In this paper, we consider the frequency characteristics of the diffracted fields not only outside but also inside the transition...
