%X In this paper, an accurate and efficient implementation approach of the Method of Moments (MOM) is developed to compute scattering from 3-D targets in the subsurface, which is based on the Mixed Potential Integral Equation (MPIE) in layered media and the RWG basis function. The implementation skill and computing performance of the proposed approach are studied in detail. In particular, how to efficiently calculate various different Sommerfeld integrals (SIs) is numerically investigated with the discrete complex images technique. The computed results of the targets in free space are in agreement with Mie Series results and the computed results of subsurface flat are also in agreement with the published data, which shows the reliability, efficiency and accuracy of the developed approach. Furthermore, the EM scattering of other shaped targets is computed at different size, buried depth, and subsurface medium.
