Abstract:
Stationary problems for the diffraction (tunneling) of a plane electromagnetic wave through a layer of matter with dielectric properties, as well as a quantum particle tunneling through a rectangular potential barrier are considered. It is shown that there are no superluminal motions, and the transit time is always longer when the wave passes the structure at the speed of light.
Keywords:energy velocity, tunneling time, frequency dispersion, Bohm–Wigner time, Hartman paradox.
