Abstract

The adaptive integral method (AIM) is used to accelerate the iterative method-of-moments (MOM) solution of the frequency-domain surface-volume electric-field integral equation pertinent to the analysis of antennas near realistic human models. The iterative solution convergence is improved by using a block diagonal preconditioner: One block of the preconditioner contains the full inverse of the surface-tested portion of the MOM impedance matrix; the other block contains the diagonal inverse of the volume-tested portion. Various antenna-body configurations are simulated.
