An explicit and unconditionally stable time-domain finite-element method of linear complexity for electromagnetics-based simulation of 3-D global interconnect network

An explicit and unconditionally stable time-domain finite-element method of linear complexity is developed for the simulation of 3-D global interconnect network Numerical experiments have demonstrated that the proposed unconditionally stable explicit method outperforms both the conditionally stable explicit method and the unconditionally stable implicit method in computational efficiency.
