Solution of the Boundary Integral Equation in Time Domain Based on the Laguerre Polynomials
基于Laguerre多项式的边界积分方程时域求解

In order to eliminate the late-time-oscillate in time domain integral equation, EFIE, MFIE and CFIE which based on the method of MOD using Laguerre polynomials as temporal basis function were introduced, induced current distributing and backward scattering of far field in time domain and monostatic RCS of a conducting sphere and a cylinder were given. The results showed that they eliminate the late-time-oscillate effectively and the CFIE has higher precision than the other two.
