Abstract
The conditions for resonance and signal cutoff are determined from the dispersion relation for the complex refractive index for a plane electromagnetic wave propagating in a gas-discharge plasma when a magnetic field H = H0 + H1ejΩt is imposed on the plasma. The refractive index and absorption are calculated for circularly polarized waves as functions of the alternating magnetic field with ωp, ωb, andv as parameters. Possible observation of modulation of the transmitted signal is demonstrated.
