Abstract

Approximate time-domain relations between the electric field integrated along the edge and the magnetic flux density integrated over the facet of the computational cell at the dielectric/conductor interface are derived and implemented into the finite integration technique to accurately eliminate the conducting region from the computational mesh. Both Cartesian and tetrahedral grids are considered. A numerical example is included to illustrate the method
