Implicit scheme time domain BEM analysis of transient electromagnetic fields

This paper discusses boundary element (BE) analysis of the transient electromagnetic fields scattering phenomena. Especially, an implicit scheme formulation is introduced to achieve stable calculations. The formulation is done based on the inhomogeneous wave equation to the scalar and vector potentials of electromagnetic fields. The discussion shows us the boundary integral equations which appear in the formulation have clear physical meaning, although potentials are used there. After formulation, some numerical simulation examples are also shown to confirm the validity of the formulation.
