Abstract :
The use of wavelets in Galerkin scheme moment methods significantly reduces computation time and memory requirements. An a priori estimation of the number of entries of the system matrix is presented. The wavelet scheme is particularly advantageous when analyzing electrically small but complex structures. While normally O(N/sup 2/) elements need to be stored, wavelets allow a reduction to O (N log N) with N the number of unknowns.
