Abstract:
A novel hybrid Fast Physical Optics (FPO) algorithm for the analysis of dual reflector antennas is presented. A two-level FPO algorithm for the subreflector to main reflector propagation is proposed and combined with the multilevel FPO that is used for the main reflector to far-field computation. The accuracy of the proposed method is studied by comparison with the direct physical optics evaluation of the near and far fields.
