Domain decomposition techniques for the scattering by partly BOR objects Application to the “antenna-radome” modeling

This paper presents a numerical method to compute the radiation pattern of an antenna placed behind a radome, which is a body of revolution (BOR). The method is based on boundary element methods (BEM): a free-standing antenna is calculated by a domain decomposition technique and appears as an excitation term of a free-standing radome problem, which is treated by a BEM specific to BOR.
