Stability of Classical Finite-Difference Time-Domain (FDTD) Formulation with Nonlinear Elements --- A New Perspective

In this paper new stability theorems for Yeeʹs Finite- Difference Time-Domain (FDTD) formulation are derived based on the energy method. A numerical energy expression is proposed. This numerical energy is dependent on the FDTD modelʹs E and H field compon
