In particular, recently developed formulations increase the stability of the resulting matrix equations, hence they are more suitable for iterative solutions [1]. Among those formulations, we consider the combined tangential formulation (CTF), which produces more accurate results, and the electric and magnetic current combined-field integral equation (JMCFIE), which produces better-conditioned matrix systems than other formulations [1, 2]. ©2010 IEEE.EnglishCombined field integral equationsIterative solutionsMagnetic currentsMatrix equationsMatrix systemsMulti-level fast multi-pole algorithmPreconditionersSchur complementSurface integralsAntennasConference Paper10.1109/APS.2010.5561865
