The whole computational domain is split into two subsystems: one is the EM subsystem that is analyzed by DGFETD, while another is the circuit subsystem that is modeled by the Modified Nodal Analysis method to generate a circuit subsystem. The coupling between the EM and circuit subsystems is achieved through a lumped port. Due to the local properties of DGFETD operations, only small coupling matrix equation systems are involved. To handle non-linear devices, the standard Newton–Raphson method is applied to the established non-linear matrix equations. Numerical examples are presented to validate the proposed algorithm.Read More
