Tunneling time of electromagnetic pulse through plasma: numerical experiment

Abstract

Plasma is a basic example of the tunneling effect in electrodynamics, however, to date there are no systematic studies of electromagnetic radiation tunneling in plasma. Discussion of various approaches to studying this issue leads to the need for a thorough solution of the non-stationary problem of electromagnetic pulse propagation in plasma /1/. In this paper, the propagation of electromagnetic pulse is numerically investigated by the finite-difference time-domain (FDTD) method /2/ for solving Maxwell's equations, using an open-source software package /3/. The dispersive character of medium is treated via using an additional equation for polarization.
