✦ Synopsis

A new point of view based on a "nite element formulation for solving Maxwell's equations in the time domain is presented to deal with grid re"nements in FDTD. The formulation allows the coupling of non-conforming structured or unstructured meshes. As a special case, it can advantageously derive stable space}time subgridding schemes in FDTD. Numerical experiments demonstrate the e$ciency and the validity of the technique.

This paper presents a 3D body-conforming "nite element solution of the time-dependent vector wave equation. The method uses edge elements on tetrahedra for the electric "eld interpolation. This kind of element is suited to model Maxwell's equations since it only enforces tangential continuity of vec
