| Popis: | The moment of method (MoM) is often used to calculate the EM scattering characteristics from a rough surface. However, the MoM needs to calculate the full matrix with larger dimension, which is often time-consuming. In this paper, the two integral equations based on the principle of field equivalence and combined with the characteristic basis function method (CBFM) is proposed to solve the EM scattering problem of one-dimensional dielectric rough surface. The two integral equations using pulse basis function after the formation of the impedance matrix has good numerical performance, and based on the surface is blocked, the dimension of the actual calculating matrix is reduced. The scattering coefficient calculate by the CBFM mentioned can be good agreement with the results obtained by the conventional MoM. |
