摘 要:The volume-surface integral equation(VSIE) ,the surface integral equation(SIE) and the volume integral equation(VIE) of EM scattering problem are converted into linear equations with the method of moment,then the precorrected-FFT method is used to solve the linear *** overcome the drawback of conventional stencil topology,two kinds of improved stencil topology,stencil topology B and stencil topology C,are presented,and the construction and actual performance of the three kinds of stencil topology are *** results show that good agreement is observed between the P-FFT solutions combined with each of the three kinds of stencil topology and the standard *** B can significantly reduce the number of near-zone *** C potentially holds for parallel multilevel P-FFT since grid overlapping never occurs between any stencils.
