Abstract :
In this paper, a computationally efficient method of moments (MoM)-physical optics (PO) formulation of the general paraboloidal reflector antenna problem is developed. The formulation hybridizes the integral equation approach characteristic of the conventional ‘low-frequency’ methods and the asymptotic solution of the wave-object interaction problem of PO. This formulation is based on an adaptation of an approach prescribed by Kerdemilidis - for a parametric description of the antenna’s geometry - leading to a generalization in a relatively simplified format of an ordinarily analytically involved process. The obtained results show a good agreement with the reported results due to other approaches and, consequently, prove the validity of the proposed model.
