This function performs one-dimensional (Cartesian) finite-difference time-domain simulations. It assumes the spatial grid extends from k = 1 to k = Nz and that the simulation runs for nSteps time steps.(1D-FDTD-program(matlab) This function performs one-dimensional (Cartesian) finite-difference time-domain simulations.
