In this paper,the adaptively modified characteristic basis function Method(AMCBFM) is proposed to fast simulate the electromagnetic scattering from one-dimensional rough ***,the Primary characteristicbasisfunctions(PCBFs) arising from the self-interaction within the self-block are generated,and the coefficients of the basisfunction and the first current of each block are ***,the Secondary characteristicbasisfunctions(SCBFs) which account for the mutual coupling effects from the other distinct domains are obtained by using the *** higher SCBFs can be also derived through the same ***,a new precision method is applied to control the current error,which is used to determine the order of the higher order *** Comparing numerical simulations through the AMCBFM and the traditional characteristicbasisfunction Method(CBFM),the AMCBFM can guarantee the accuracy and void higher iteration,and the convergence performance is better than the CBFM in the lower order ***,by comparing numerical results of the AMCBFM and the method of moments(MoM),the AMCBFM can effectively reduce the size of the impedance matrix,and significantly reduce computing time.

In this article, we present a novel approach based on PMCHW integral equation formulation in conjunction with the adaptively modified characteristic basis function method (AMCBFM) to solve the scattering from homogenous dielectric bodies. In the new method, equivalent electric and magnetic currents on the surface of object are needed and expanded using RWG basisfunctions. AMCFBM is subsequently used into the former matrix equation. The studied object is partitioned into distinct blocks with some overlapped-domains between neighboring ones. The matrix equation is solved by direct solution instead of iterative methods. The compatibility, accuracy and efficiency of this novel approach are demonstrated by a variety of scattering problems.
