A Hybrid DGTD and FDTD-TL Method for Solving Field-to-Wire Coupling Problems

To efficiently assess the impact of field-to-wire coupling problems in a multiscale structure, a hybrid discontinuous Galerkin time domain (DGTD) and finite difference time domain with transmission line (FDTD-TL) method is proposed in this article. Specifically, the EB scheme DGTD method is utilized to calculate electromagnetic fields in the multiscale region, while the FDTD-TL method is employed to establish connections between the electromagnetic fields and wires based on the Agrawal model.
