© 2021 IEEE.We present a novel combined potential-field formulation (CPFF) for rigorous analyses of electromagnetic problems involving closed conductors with various dimensions and arbitrarily dense discretizations. The formulation is based on the recently developed potential integral equations (PIEs) combined with the magnetic-field integral equation, as well as with another potential-based integral equation to reach resonance-free, low-frequency-stable, and iteratively efficient solutions using conventional discretization functions. Numerical examples demonstrate the superior performance of CPFF in comparison to other available formulations, particularly for challenging problems involving densely discretized structures and large numbers of unknowns.
