Abstract :
The electromagnetic (EM) scattering and shielding properties of structures above a lossy half space have been studied by many investigators. Baertlein (1988) introduced a moment method (MM) solution with a surface formulation and the spectral domain Green´s function for two-dimensional (2-D) perfect electric conductor (PEC) structures over a lossy half space to study the shielding effectiveness of the PEC plates above the ground. This article presents an MM solution to evaluate the EM shielding properties of three-dimensional (3-D) objects over a lossy half space. The MM with the volume formulation and 3-D Green´s functions in the spectral domain is developed, where the 3-D objects can be composed of metallic, dielectric, or magnetic materials.
