In this article, the electromagnetic analysis of arbitrarily shaped three‐dimensional homogenous dielectric objects located above a lossy half space is considered with a well‐conditioned surface integral equation. The electric‐magnetic current combined‐field integral equation (JMCFIE) is extended to the half‐space situation to realize accurate and fast solution. This formulation can lead to a well‐tested equation system with the RWG basis functions and Galerkin's testing procedure. The multilevel fast multipole algorithm (MLFMA) accelerated inner‐outer Flexible Generalized Minimal Residual method (FGMRES) is used for the efficient solution. Numerical results demonstrate the accuracy and high efficiency of this method. © 2009 Wiley Periodicals, Inc.
