Web波导（WAVEGUIDE），是用来定向引导电磁波的结构。在电磁学和通信工程中，波导这个词可以指在它的端点间传递电磁波的任何线性结构，最初和最常见的意思是指用来传输无线电波的空心金属管。波导主要用作微波频率的传输线，在微波炉、雷达、通讯卫星和微波无线电链路设备中用来将微波发送器 ... WebMost waveguides exhibit two-dimensional guidance, thus restricting the extension of guided light in two dimensions and permitting propagation essentially only in one dimension. An example is the channel waveguide shown in Figure 1. The most important type of two-dimensional waveguide is the optical fiber.
