Abstract

An analysis of thin-wire antennas and scatterers is developed by using orthogonal wavelets on [0,1]. A sparse matrix equation is attained from the thin-wire electric-field integral equation (EFIE) by using this technique. The matrix obtained from this technique exhibits a multi-level structure as well. This multilevel structure greatly speeds up the solution of the matrix equation. Numerical examples are presented to illustrate the accuracy and merits of this approach.
