摘要
给出了有限磁场下波在等离子体填充的波纹波导中传播的分析理论。推导出作为普遍严格公式的场分量的弗洛奎展式、本征值表达式以及色散方程。在某些特定情况下，详细讨论了波传输功率和耦合系数，这对于波纹结构的进一步研究非常有用。同时给出了初步的数值计算。其结果表明外加磁场的场强对波传播的色散特性有很大的影响从而影响了这类器件的性能。
Analytical theory of wave propagation along a corrugated waveguide filled with Plasmas immersed in a finite axial magnetic field is presented in this peper. Floquet's egunsion of field components,eigen values and dispersion equations as rigorous and general formulas are derived. For some special cases,wave power transmission and coupling coefficients are invedignted in derail, which are useful for further study of such corrugated structure. Preliminary numerical calculations are also done. It is shown that the nitensity of magnetic field has considerable influence on the dispersive characteristics of wave propagation and the properties of such devices.
