Topics in Guided-Wave Propagation Through Gyromagnetic Media

The characteristic equation for the propagation constants of waves in a filled circular guide of arbitrary radius is written in terms of magnetizing field and a carrier density, which are shown essentially to determine the dielectric and permeability tensors for a gas discharge plasma and for a fertile. The complex structure of the spectrum of propagation constants and its dependence upon radius and the two parameters are analyzed by a semigraphical method, supplemented by exact formulae in special regions. Thus the course of individual modes may be charted with fair accuracy.
