Abstract :
Using the recently developed method based on the rigorous theory of singular and hypersingular integral equations (IEs) and Nystrom-type discretization, a paraboloidal reflector assisted with a conical shield is investigated. To decrease the computation time we propose a new method of calculation of the Modal Green´s Functions in the quasi-optical range. The far and near fields of the studied reflector are analyzed in the transmission and reception cases, and reveal fine features that escape asymptotic analysis. Elementary numerical optimization of the shield-assisted paraboloidal antenna is performed.
