Electromagnetic scattering by an object buried in soil

This paper investigates the scattering of electromagnetic waves by an object buried in soil. We use the finite difference time domain (FDTD) method to compute the scattered electric fields and power density on the soil surface, in the soil around the object, and in the object We consider a dielectric object, a metallic object, as well as a dielectric object with a thin metallic pin. We determine the effect of various parameters including the incident wave frequency, the object depth, the object dielectric properties, and the soil dielectric properties, on the scattered fields at various locations.
