PROPAGATION OF WAVES IN INHOMOGENEOUS MAGNETO-ACTIVE PLASMA COLUMNS
Abstract
Starting from Maxwell's equations, a general investigation of the propagation of a quasistatic E mode in a plasma column with non uniform electron density distribution in the cross-section, is considered, where a parabolic distribution has been taken as an analytical model for the electron density profile in the cross-section. Electron density is supposed to vanish at a point outside the plasma column; in the limit for the zero point to go to infinity, uniform case equations are obtained. Letting the metal walls move to infinity, or coincide with the plasma boundary, the completely filled wave guide and the plasma column in free space dis persion curves have been verified. The Ritz variational method is used to minimize the error over the cross section when an approxi mation function for the field distribution in the plasma is assumed.
