Abstract

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 horizontal edges with an arbitrary angle which are in different and same heights, when a source is located lower than the height of the edges. In this paper, we compare the strength of the direct field, single and double diffracted fields, when the height of the source is varied. Furthermore, the effect of frequency change to the diffracted field is discussed. The numerical calculations are carried out for two wedges and a building-like double-wedge on perfect conductor, concrete and earth wedges. The results show that the higher the source is located, the stronger the diffracted fields become, and the frequency change has not a significant effect to the total field.
