Abstract

The hybrid ray-finite difference time domain (FDTD) is used for the propagation of electromagnetic pulse in homogeneous and inhomogeneous media. This method is cast in the Lagrange formulation, where the field equations are transformed into a moving frame. The moving frame formulation is extended to 3D and applied to track propagating wavepackets. The numerical dispersions and the stability conditions are derived using a unified approach. Boundary conditions for the moving frame scheme are derived by diagonalizing the field equations, identifying the backward propagating and stationary eigenfunctions as the basic two independent unknowns and imposing numerical absorption or specification.
