Abstract :
In this paper, the implementation of a Fourier-Jacobi surface expansion into a geometrical optics/physical optics (GO/PO) reflector analysis is discussed and some unique features of this implementation are detailed. The radiation characteristics, such as directivity or farfield patterns, of a dual reflector antenna are calculated from the main reflector PO currents.
