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.
In this work, the two- and multi-level Fast Physical Optics (FPO) algorithms recently proposed by the authors [1], [2] are combined to compute the radiation patterns of dual reflector antennas.
