Abstract

The multipole method is firstly used to accelerate the radiation analysis of the dual reflector antenna with the double-bounce physical optics. The algorithm starts with physical optics to calculate the equivalent electric current on the subreflector. Then the equivalent electric current on the main reflector can be obtained through the current on the subreflector. It should be noted that the modified multilevel fast multipole method (MLFMM) is applied to accelerate the calculation between the main reflector and the subreflector. In this way, the computation complexity is reduced greatly, thus the computational time can be significantly saved. At last, numerical results are given to demonstrate the superior efficiency and accuracy of the proposed method.
