Abstract :
The application of an iterative method based on the wave concept to model planar circuits using a multiscale grid is investigated. The novelty of this method consists in substituting selected coarse meshes by their equivalent surface impedances. This approach offers high spatial-resolution with low computing resources, and results are presented to demonstrate its efficiency.
