Abstract
The hybrid volume-surface integral equation (VSIE) combined with the Method of Moments (MoM) is applied to the analysis of scattering from arbitrarily composite conducting-dielectric objects withconducting-dielectric or dielectric-dielectric junctions. The electric field volume integral equation is applied to the material region and the electric field surface integral equation is enforced over the conducting surface. Compared to the surface integral equation (SIE), the VSIE is more efficient and convenient since the formulation of the VSIE retains the same simple form regardless of the complexity of the object and materials, and no extra treatment is required when dealing withjunction problems.
