| Abstract: | Based on the feature that impedance matrix was independent from the incident angle in the meth od of moments （MOM）, this paper proposes a method that brings compressive sensing （CS） technique into electromagnetic problem in order to reduce the computing time without sacrificing much accuracy. This method combines compressive sensing with compute unified device architecture （CUDA） technique to solve the electromagnetic scattering problem over wide angle by parallel computing in graphic processing unit （GPU）. It is shown in numerical experiments that comparing with traditional algorithm the proposed method saves much computing time, and the accuracy can also be accepted. |
