%X Forward electromagnetic scattering by buried objects is computed with the integral equation method and efficient algorithm for half-space dyadic Green's functions. Firstly, half-space dyadic Green's functions are given to establish the integral equation for buried dielectric objects. After getting the spatial differential operator out of the integral sign and computing the rest with the discrete complex image method, a closed form of Green's functions can be obtained. The avoidance of numerical evaluation of Sommerfeld integrals overcomes the bottleneck probably resulted from the calculation of Green's functions when filling reaction matrix and calculating scattering electric fields. The proposed method enhances the efficiency of forward calculation of buried dielectric objects and acceptable accuracy can be guaranteed.
