Abstract

The aim of this work is to implement a hybrid approach able to provide an efficient solution of the electromagnetic coupling between an antenna and an obstacle distant few meters away. The idea is to divide the problem into a small number of less complex sub-problems exploiting the advantage of generating the admittance matrix that describes the scattering problem by a numerical code. To this end, the electromagnetic field impinging on the object has been characterized by means of a proper number of very narrow beams; for each beam the scattering problem has been solved by a commercial code; finally, the total admittance matrix has been obtained as composition of all the scattering contributions. The resulting echoof a moving obstacle has been compared with that measured by experimental investigations, both for metallic and dielectric bodies.
