A KIRCHHOFF INTEGRAL APPROACH FOR DECIMETRIC RADIOWAVE PROPAGATION IN URBAN AREAS

摘要

We consider a three-dimensional approach based on the Kirchhoff’s method in order to predict electromagnetic waves propagation in urban environments. In particular, we are interested here in the evaluation of the electro-magnetic field on very large three-dimensional domains (typically with linear dimensions of the order of hun-dreds of meters) generated by a high frequency source (typically of the order of 1GHz which corresponds to a wavelength of about 30 centimeters). Some numerical tests and comparisons with experimental measurements have been done to validate this approach.
