MODELING OF ELECTROMAGNETIC WAVE SCATTERING BASED ON THE COMBINED METHOD IN URBAN AREAS
V.G. Panarin, A.G.Yurochkin
The paper discusses a combined model of electromagnetic wave diffraction by buildings in urban areas, is based on the uniform theory of diffraction. It is known that there are problems when using the uniform theory of diffraction for areas in which there is a large number of wedges. In the present work is the consideration of the members of the high-order diffracted field, giving opportunities for more accurate results, that is, using a combined model with physical optics and uniform theory of diffraction. Such models may find applications in the development of theoretical models to predict more accurate way signal loss in urban environments when considering the propagation in several buildings.
