| Abstract: | This paper develops a numerical model for investigating the electro- magnetic scattering by a rectangular inhomogeneity in the presence of an interface between two different media.A method for making the computer program universal is given.The approximate method for evaluating the integrals of the Green's functions is considered.Some calculated results upon the physical model of underground-two-hole-EM wave method are given.The measured result of the scattered field by a dielectric object under a water surface verifies the numerical model. |
