波导管

波导管是一种用于传导高频电磁波的组件,和同轴电缆相似,只是其传输的电磁波频率更高。波导管有很多形式,最常见的是一个空心金属管,用于传导微波(电磁波导)

波导管有多种几何形状,用于控制波的传播方向,比如一维的板状,二维的管/棒状。此外,不同的波长需要不同的波导管:光需要用光纤传导,而光纤不能传播微波。根据经验判断,波导管的直径需要和传播的波长在同一个数量级。

波在波导管中的传输近似于全反射,所以波在其中的传播像是一条“之”字体路线。

Waveguide 波导管

A section of flexible waveguide with a pressurizable flange
Electric field Ex component of the TE31 mode inside an x-band hollow metal waveguide.
Example of waveguides and a diplexer in an air traffic control radar
Waveguide supplying power for the Argonne National Laboratory Advanced Photon Source.

A waveguide is a structure that guides waves, such as electromagnetic waves or sound waves. They enable a signal to propagate with minimal loss of energy by restricting expansion to one dimension or two. This is a similar effect to waves of water constrained within a canal, or why guns have barrels that restrict hot gas expansion to maximize energy transfer to their bullets. Without the physical constraint of a waveguide, signals will typically dissipate according to the inverse square law as they expand into three dimensional space.
