%X Differential scattering field of vertical incident Gaussian beam from a two-dimensional target near a plane interface is studied by means of a new hybrid method based on the reciprocity theorem (RT), the image theory (IT) and the method of moment (MoM). By application of IT, the plane interface is replaced by the virtual image of the actual target, and an equivalent model of the scattering problem is presented. In the equivalent model, the scattered field from the actual target and the virtual one are numerically calculated by employing MoM, and the rescattered coupling fields between the actual target and the virtual one are evaluated utilizing the combination of MoM and RT. The numerical results of these tests are presented and compared with previously published calculations for the same problems.
