Abstract :
A multilevel fast physical optics (FPO) algorithm for computation of the radiation patterns of reflector antennas via hierarchical domain decomposition is presented. Numerical results demonstrate that, even with a simple cubic interpolation, the proposed FPO approach provides a large speedup without degrading the accuracy of the resulting radiation patterns.
