Abstract
The Control Region Approximation is a generalized finite-difference procedure that accomodates completely general geometries and materials. It involves the discretization of conservation form equations on Dirichlet/Delaunay tessellations. This ensures the satisfaction of appropriate jump conditions across interfaces and permits a straightforward application of relevant boundary conditions. After presenting the basics of this discretization strategy, this paper details its application to electromagnetic scattering computations. Specific application is made to
-
two-dimensional frequency-domain simulation,
-
two-dimensional time-domain simulation,
-
three-dimensional frequency-domain simulation,
-
two-dimensional periodic structures.
Finally, related ongoing work is described.
