摘要

从理论上研究了由反向波数的螺旋谐波叠加形成的体势波在磁化等离子体柱中的传播。体波的谱是按高斯密度分布计算的。结果表明，在一定频率下，具有真空间隙的金属波导中等离子体的径向非均匀性导致体波模式垂直于波导轴的旋转方向发生变化。

Rotation of Bulk Potential Waves in Cylindrical Waveguide with Partially Inhomogeneous Plasma Filling

Propagation of bulk potential waves formed by superposition of helical harmonics with opposite azimuthal wavenumbers in a column of magnetized plasma is studied theoretically. The spectrum of bulk waves is calculated for a Gaussian density distribution. It is demonstrated that radial inhomogeneity of plasma in a metal waveguide with a vacuum gap at a certain frequency leads to a change in the direction of the bulk wave pattern rotation perpendicular to the waveguide axis.

期刊介绍： Plasma Physics Reports is a peer reviewed journal devoted to plasma physics. The journal covers the following topics: high-temperature plasma physics related to the problem of controlled nuclear fusion based on magnetic and inertial confinement; physics of cosmic plasma, including magnetosphere plasma, sun and stellar plasma, etc.; gas discharge plasma and plasma generated by laser and particle beams. The journal also publishes papers on such related topics as plasma electronics, generation of radiation in plasma, and plasma diagnostics. As well as other original communications, the journal publishes topical reviews and conference proceedings.
