Azimuthal surface waves are well-known to be eigenwaves of coaxial metal waveguides entirely filled by plasma. The present study of electromagnetic energy transfer complements the investigation of the wave dispersion properties carried out earlier. The angular velocity of energy transfer is analyzed as a function of the coaxial-line parameters and compared with three limiting cases. One case is a metal waveguide entirely filled by plasma. The second case is a metal rod placed into infinite plasma along an external static magnetic field. Finally, the third one is a thin coaxial waveguide.

在完全由等离子体填充的同轴金属波导中由方位角表面波引发的电磁能旋转

众所周知，方位表面波是完全由等离子体填充的同轴金属波导的本征波。目前对电磁能量转移的研究是对早先进行的波色散特性研究的补充。能量传递的角速度被分析为同轴线参数的函数，并与三个极限情况进行比较。一种情况是完全由等离子体填充的金属波导。第二种情况是将金属棒置于沿外部静磁场的无限等离子体中。最后，第三个是细同轴波导。
