Characteristics of waveguides filled with homogenous lossy anisotropic drifting plasma.

In this paper the dispersion relation for rectangular waveguides filled with homogeneous lossy drifting plasma under the influence of infinite longitudinal magnetic field is derived and discussed. The properties of TE modes are found to be the same as those of air-filled guides. However, uniaxial anisotropic drifting lossy plasma has a significant effect on the propagation characteristics of TM modes. A comparison of the effects and physical significance of the changes duo to isotropic and anisotropic plasma models is discussed.
1. Introduction
In recent years plasma-filled waveguides have received considerable attention owing to their applications in microwaves. A general solution for the propagating modes in waveguides completely or partially filled with plasma, taking into account an applied static magnetic field, non-uniform density over the guide cross section and non-vanishing temperature, has not yet been found. It is customary to incorporate the effect of plasma by assuming either an equivalent dielectric constant in the absence of an external magnetic field or an equivalent dielectric tensor with an external applied magnetic field. The nature of electromagnetic wave propagation in waveguides filled with cold stationary plasma under the influence of an external magnetic field was the subject of extensive investigation (Allis et al. 1963). Recently Tuan (1969) and Kalluri (1970) have given some idea of the propagation of electromagnetic waves in waveguides filled with warm and drifting plasma. It is the purpose of the present paper to study the dispersion relation in rectangular waveguides filled with homogeneous drifting lossy uniaxial anisotropic plasma. The strong static magnetic field is assumed to be in the direction of the guide axis. [ABSTRACT FROM AUTHOR]
