When the external RF frequency is much bigger than ion plasma frequency, ions answer average field.
当外加射频频率远大于离子等离子体频率，离子响应平均场，离子的密度分布几乎不随时间变化；
The pass band of this mode is from static to plasma frequency, and does not depend on structure dimension.
这一模式的通带从零到等离子体频率，而且不依赖于结构尺寸。
However, phase speed depends on plasma frequency and structure dimension, and very slow waves can exist in very small sized waveguide.
然而，波的相速依赖于等离子体频率和结构尺寸，并且非常慢的波可以存在于非常小尺寸的波导中。
