A Simple Approach to Determine the Buried Object under the Ground

The study aims to determine the buried dielectric object under the ground based on the frequency characteristics of the object. To achieve that goal, a minimum reflection angle - Brewster angle is found when there is no object in the region of interest. Then, the electromagnetic propagation with the obtained angle is employed when the object exists. The reflected field reveals the resonances of the object and by comparison, the physical properties of the unknown object can be predicted. To achieve this goal using computer simulation, the Method of Auxiliary Source (MAS) is employed.
