Abstract :
The dispersive boundary condition (DBC) is a versatile boundary condition in that it can be used for radiation problems as well as for guided-wave problems. The DBC is applied to nonuniform meshes and various implementations are reported. Stability issues are discussed and numerical results are presented for a microstrip line and for a point source radiator. Error analysis is carried out in the time and frequency domains
