Galerkin operators in adaptive integral method implementations

The adaptive integral method (AIM) is a fast method associated with O(N^1.5) or less complexity. It has been extensively used for the analysis of metallic scatterers on the basis of the electric field integral equation (EFIE), and the AIM implementation is extended to include more general surface types such as impedance, resistive, dielectric and others. The associated multipole expansions of the basis functions are presented for all integral operators, and examples of perfect electrically conducting (PEC) and dielectric surfaces are given for validation
