Calculation of scattered TMz waves from a cylindrical dielectric scatterer buried inside a lossy ground

A new numerical solution method is summarized for the problem of electromagnetic scattering from a cylindrical object of arbitrary cross-section buried in a lossy dielectric half-space that is considered to be flat. The surface equivalence principle and a decomposition method are employed to form a set of electric field integral equations (EFIEs) for the currents on the object and the portion of the surface most strongly interacting with the object. The Method of Moment (MoM) is used to solve the EFIEs in the frequency domain to obtain the scattered electric field.
