In this Letter a new type of combined field integral equation (CFIE) is proposed and applied for electromagnetic scattering by three‐dimensional dielectric objects of arbitrary shape. In this formulation, traditional CFIE is applied outside the object, and inside the object the electric and magnetic field integral equations are combined by changing their roles. This formulation gives a more stable solution than the traditional CFIE when the method of moments with Galerkin's type testing and RWG functions is applied. © 2002 Wiley Periodicals, Inc.
