Microwave communications in real urban conditions

The problem of distribution of electromagnetic waves in range 200-4500 MHz along a surface with deep modulation of a relief is reviewed in case when the source of radiation is located on border or it is directly situated in the area of spatial modulation of a relief. The methods used for the decision of similar problems are analyzed, their comparative analysis is conducted, conditions and limits of applicability are investigated. The new theoretical concept of distribution of electromagnetic waves in conditions of an actual urban or geographic landscape founded on a hypothesis of the resonant interaction of electromagnetic fields with low intensity high harmonics of Fur'e-decomposition of a surface relief is offered. The theoretical model and the mathematical method of the description were developed.
