Faraday tarotion: New parameter for electromagnetic pulse propagation in magnetoplasma

Extreme distortion and time-dependent Faraday rotation occur for propagation of short electromagnetic pulses in magneto-plasma, for some ranges of plasma parameters. In order to relate pulse and monochromatic waves for propagation-path diagnostic purposes, we introduce a new parameter for the transmitted pulse train which has properties that correspond very accurately to results that would be expected for Faraday rotation of a continuous wave having the central frequency of the incident pulse spectrum. Results for 5-ns pulses (10 GHz) are presented for varying propagating length, static magnetic field, electron density, and collisional absorption.
