Abstract
In this paper, we consider solutions of a real-life dielectric problem using CTF and JMCFIE formulations. We offer two novel preconditioners, namely ASP and ISP, to overcome the convergence problem. The matrix equation obtained from JMCFIE benefits more from preconditioning and it is solved faster than the one obtained from CTF. However, a comparison of the near-zone fields shows that solutions obtained with JMCFIE may not be reliable for the analysis of real-life problems that involve complex shapes and high dielectric constants.
