JJEE. 2020; 6(4): 348-361 A Hybrid-Analytical-Model for the Paraboloidal Reflector AntennaFrancis Okewole, Ayotunde Ayorinde, Sulaiman Adeniyi Adekola, A. Ike Mowete. 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 antennas 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.
