Abstract :
In this paper, we apply the adaptive integral method (AIM) to the solution of the combined field integral equation (CFIE) and study the convergence behavior of AIM as applied to the electric field integral equation, the magnetic field integral equation and CFIE. The memory requirement and computational complexity of the AIM solution of CFIE are O(N/sup 1.5/) and O(N/sup 1.5/logN) for 3D surface scattering problems. The numerical results demonstrate that the AIM solution of CFIE is efficient for the analysis of scattering from arbitrarily-shaped 3D conducting structures.
