 A higher-order geometry modeling technique is presented for the solution of volume integral equations (VIEs) involving arbitrarily shaped inhomogeneous dielectric structures. Conformal basis functions defined in curved hexahedral finite elements are used to develop a moment method solution of the VIE. Results are compared with available analytical solutions, and the method is shown to deliver higher accuracy using coarser meshes as compared to partial differential equation solvers.
