Abstract : The objective of this research is to study the feasibility of computing electromagnetic wave scattering by objects which are buried or partially buried in a lossy ground. The datas obtained through computer solutions of the related Maxwell's Equations can be applied to detection of plastic land mines, tunnels and natural resources. The method used in this investigation is based on the Unimoment method, a unique hybrid of analytical and numerical methods. The extension of the method to include lossy ground half-space was made possible by the development of special eigenfunctions which include the continuity of the air-ground interface. Results were obtained for scattering by buried body of revolution, buried body of revolution with arbitrary orientation and two-body scattering.
