Global numerical boundary condition based PDE solution techniques for open-region electromagnetic field problems

The underlying concept and algorithm for global numerical boundary condition (GNBC) based PDE solution techniques for open-region EMF problems are presented. This numerical procedure has been applied with success for various boundary-value problems in scattering, waveguide, and radiation analysis showing distinct advantages in generality, flexibility, and simplicity. All the GNBCs treated are of the first kind, i.e. eigenfunction-based GNBCs.<
