Abstract :
A transient non-conformal domain decomposition scheme is proposed. The proposed scheme is based on the unconditionally stable Laguerre-FDTD method. A mortar-element-like method is applied and the field continuity at the non-conformal domain interface is enforced by using the Lagrange multiplier. The Schur complement method is used for addressing the interface problem. Simulation results have been presented to demonstrate the accuracy and efficiency of the proposed scheme.
