Abstract

Mur's second order Radiating Boundary Conditions were developed for use with uniform grids in homogeneous media only. This paper shows that the algorithm can be adapted for use with non-uniform grids and inhomegeneous media in the boundary plane. Reductions in the order of 80% of memory and CPU time have been achieved for the model of an infinitesimal dipole between and infinite substrate and superstrate, compared with a model using a uniform grid.
