The Effect of the Width of the Incident Pulse to the Dielectric Transition Layer in the Scattering of an Electromagnetic Pulse—A Qubit Lattice Algorithm Simulation

The effect of the thickness dielectric boundary layer that connects a material refractive index $n_1$ to another $n_2$ is considered for propagation an electromagnetic pulse. For very thin scattering properties pulse mimics found from Fresnel jump conditions plane wave - except transmission incident amplitudes are augmented by factor $\sqrt{n_2/n_1}$. As becomes thicker one finds deviations away and eventually approaches WKB propagation. However there small but unusual dip in part transmitted persists time. quantum lattice algorithm (QLA) used recovers Maxwell equations second order parameter -- QLA still when this unity. expansion speed medium $n_1$.
