Abstract :
A Multi-Resolution (MR) approach to the Electric Field Integral Equation-Method of Moments (EFIE-MoM) analysis is presented, that keeps the different scales of the problem directly into the basis functions representation. These MR basis functions possess both spectral and spatial resolution, which allows to control the matrix condition number: the obtained MoM matrix is stable against clipping sparsification, and the use of iterative solvers convenient. In this contribution the method is applied to large and complex arrays (with triangular mesh), showing high matrix sparsity and fast convergence.
