Abstract
This paper is concerned with a theoretical solution to the problem of TE-Scattering radio waves by a buried object in a three-layered medium. The region of interest consists of three homogenous layered medium, the object of an inhomogeneous material with respect to its layer. With the aid of geometrical optics technique, this paper analyzes the influence of the buried object on the scattered magnetic field from the layered medium. Closed-form expressions for the far-field of a VMD, located above the ground surface, are obtained due to the buried object under the ground. This technique takes into consideration all the probabilities of plane waves under and above the ground to calculate the total reflection coefficient. The extra-scattered field due to the perturbation in the earth magnetic field has been obtained by solving Sommerfeld integrals (SI). The solution of SI has been based on the stationary-phase point method. The obtained results are compared with those mentioned in three- layered free buried objects.
