WAVEGUIDE MODES OF A WARM, TRANSVERSELY DRIFTING, ELECTRON-PLASMA WITH A STRONG TRANSVERSE MAGNETIC-FIELD

The dispersion relation of TM modes with respect to the direction of the static magnetic field is derived for a waveguide filled with warm plasma which is uniaxial and drifting in the transverse direction of the guide axis. The expressions for the fields are also derived. The propagation characteristics of TM modes are studied in detail. When the drift velocity is greater than the acoustic velocity, a new branch de-scribing the characteristics of a low-frequency propagating wave which starts at zero frequency and has at the upper limit a resonance condition is observed.
