摘要 将快速傅里叶交换(PFT)应用于广义索末菲积分(GSI)作数值求解,用以解决电磁场中埋入体散射问题的坐标转换.这比用其它的数值计算方法有更大的优越性. FFT (Fast Fourier Transform ) is used for numerical solution of GeneralizedSommerfeld Integrals (GSI) in order to solve the diffusion problem of coordinates transformationof the buried object in electromagnetic field. The method has more advantages than othernumerical calculations.
