Cyclotron and upper hybrid resonance frequency in reflected pulse by magnetoplasma half space

Abstract

Reflected waveforms of impulsive plane waves incident on a homogeneous lossless magnetoplasma half space (with d.c. magnetic field perpendicular to the propagation vector) are determined in the closed form by Bessel functions of first kind and fractional order. The cyclotron plasma frequency is related to the first normalised maximum excursion in the reflected waveforms. Cyclotron and upper hybrid resonance plasma frequencies are related to the delay of the first maximum excursion in the reflected waveforms.
