Electromagnetic Wave Reflection from an Oscillating, Collision-Free Magneto-Ionic Medium

摘要

A collision free or low collision magneto-io1ic medium is easily perturbed by a driving or pumping wave, even of moderate power. Unless the pump wave is of the longitudinal mode it will generate longitudinal electron velocities as well as differential space charge densities. These quantities, as well as the transverse, pump field electron velocities, will affect the propagation of any (low power) signal or probing wave propagating through the medium, which now has oscillating and travelling electron velocity and electron density ripples.
