Abstract:

The problem of scattering of two-dimensional structure objects is solved by the method of moment (MoM).Then a current based hybrid method combining the MoM with the physical optics (PO) approximation for two-dimensional objects is studied with a general matrix deduced.Finally,two examples are given to analyze the question of area-dividing of the hybrid method,and the dividing method proves efficient and accurate.
