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.
