Abstract :
A hybrid MoM/PO method for the analysis of multiple scattering effects between reflector and large feeds, such as dense multibeam phased array feeds or multifrequency front-ends (MFFEs) in which higher frequency feeds operate in the vicinity of an extended metal structure, has been presented and studied. This paper evaluates the accuracy and computational efficiency for the MoM/PO method with and without using a uniform plane wave approximation of the reflector scattered field.
