Abstract
The root cause of the instability is quantitatively identified for an explicit FDTD-based analysis of general lossy problems where both dielectrics and conductors can be lossy and inhomogeneous. Based on the root cause analysis, an efficient algorithm is developed to achieve unconditional stability in an explicit FDTD-based solution of general lossy problems. Numerical experiments have demonstrated its superior performance.
