PROPAGATION CHARACTERISTICS OF A MAGNETO-IONIC DUCT
Abstract
The propagation characteristics of a uniform magneto-ionic duct of circular cross-section are determined for signal frequencies smaller than the cyclotron frequencies. The ratios (plasma wavelength)/(free space wavelength) and (power flowing in the plasma/(power flowing outside) are evaluated and discussed as a function of the diameter/wavelength ratio and of the plasma permittivity, for the propagation of circularly symmetrical modes. The attenuation due to the electron-molecule collisions and the propagation characteristics of all modes, for a plasma frequency much smaller than the signal frequency, are also briefly discussed.
