Efficient implementation of a wavelet based Galerkin scheme

Wavelets can substantially accelerate the computation of planar circuits in method of moments (MoM) schemes. This contribution deals with the prediction of the significant system matrix entries, a key to numerical efficiency. Further, optimized grids for improved performance are defined. The implementation of the method is addressed. Relevant practical examples such as a coupled antenna array serve to demonstrate the advantages of the proposed approach and to illustrate some of its limits.
