Abstract
This article aims to evaluate the abilities of Gaussian beam techniques to compute the interaction between an electromagnetic field and a multilayer dielectric object. First, we propose an approach to expand a field on a set of elementary Gaussian beams from a curved surface. Then, we study two techniques to compute the interaction: a Gaussian beam shooting and bouncing algorithm and another original approach using the Gaussian beam transmission and reflection coefficients. We analyse the advantages (rapidity/accuracy) of these two techniques with respect to a conventional approach to compute the radiation of an antenna protected by a radome. To cite this article: A.
