Abstract
An explicit and unconditionally stable FDTD method is developed for analyzing general lossy electromagnetic problems, which preserves the diagonal property of the FDTD system in the projected space of the complex-valued stable modes. Numerical simulations of problems involving lossy and inhomogeneous dielectrics and conductors have demonstrated the accuracy, efficiency, and unconditional stability of the proposed method.
