Abstract :
The Wave Concept Iterative Procedure is an integral method based on a two equation system solution. The original formulation can be interpreted as a Richardson procedure for which the convergence condition is always satisfied despite a very slow convergence rate. In this work several improvements are presented such as an automated mesh, preconditioning and interpolation of the Richardson procedure and a similar work developed on the GMRES system solution. Performances are significantly improved with a reduction up to 96% of the number of iteration; accuracy is attested through comparison with HFSS results.
