    Abstract

    The accuracy of Physical Optics (PO) in the simulation of reflector antennas is investigated. We apply the PO approach to calculate the surface currents and far-field radiation patterns for two reflectors: a parabolic cylindrical reflector excited along its axis by an electric dipole, and a spherical reflector antenna excited by crossed electric and magnetic dipoles (Huygens source); the latter structure was also excited by a plane scalar wave. Comparisons with accurate benchmark solutions using the rigorous Method of Regularization demonstrate that the approximate PO approach is accurate enough to be used in practical antenna de sign; the mean-square error in radiation patterns is 0.05- 0.09dB.
