摘要：

In this paper, a new explicit and unconditionally stable finite-difference time-domain (FDTD) method is developed for analyzing general lossy problems. Both conductor loss and dielectric loss in inhomogeneous materials are considered. The root cause of instability is directly eradicated from the FDTD numerical system before performing explicit time marching. Numerical simulations have demonstrated the accuracy, efficiency, and unconditional stability of the new method.
