| Abstract: | Based on the finite element-boundary integral(FE-BI) method and the asymptotic waveform evaluation(AWE) technique,an efficient method for analyzing the wide-band electromagnetic scattering is proposed.Firstly,the wide-band radar cross section(RCS) of a perfectly conducting square is computed by using the proposed method,and the result is compared with that obtained by the FE-BI point-by-point method.Then the wind band RCS of the square coated with plasma of different density and collision frequency is compu... |
