Two-Dimensional Discontinuous Galerkin Time-Domain Method for Modeling of Arbitrarily Shaped Power-Ground Planes

This paper presents a two-dimensional discontinuous Galerkin time-domain (2-D DGTD) method for modeling arbitrarily shaped power-ground planes in high-speed electronics. The DGTD method has advantage over the finite-difference time-domain method in handling complex geometries, and allows high-order spatial discretization for improved accuracy. Its explicit time-stepping scheme also reduces computational cost compared to the implicit finite element time-domain method. The proposed method is validated against both measurement and commercial software to demonstrate its accuracy and efficiency.
