This paper presents an energy-based stability analysis for the classical FDTD scheme using Lyapunov functions. Following a short introduction on the Lyapunov functions, the application of the discrete counterpart is used to derive the well-known stability criterion for the FDTD method. Lossy or anisotropic (i.e. biaxial symmetry) media are seamless integrable into the derivation.
A stable and efficient extended equivalent circuit (EEC) graded mesh FDTD scheme for composite right/left-handed (CRLH) metamaterials (MTMs) is presented along with a novel stability criterion based on a Lyapunov-type energy function. This criterion is firstly derived for a purely right-handed (PRH) medium, where it has been found to be advantageous compared to the Courant condition for highly non-uniform...
