The Finite Difference Time Domain Method. The Finite Difference Time Domain (FDTD) method, as first proposed by Yee [1], is a direct solution of Maxwell's time dependent curl equations. It uses simple central-difference approximations to evaluate the space and time derivatives. A basic element of the FDTD space lattice is illustrated in Figure 2.

What is FDTD? The Finite-Difference Time-Domain (FDTD) method is a rigorous and powerful tool for modeling nano-scale optical devices. FDTD solves Maxwell’s equations directly without any physical approximation, and the maximum problem size is limited only by the extent of the computing power available.

Finite-difference time-domain or Yee's method is a numerical analysis technique used for modeling computational electrodynamics. Since it is a time-domain method, FDTD solutions can cover a wide frequency range with a single simulation run, and treat nonlinear material properties in a natural way. The FDTD method belongs in the general class of grid-based differential numerical modeling methods. The time-dependent Maxwell's equations are discretized using central-difference approximations to the
