本文导出了平面波入射到相邻阻挫全反射界面上时在薄膜波导中产生的场的表达式。从这些，我们推导出一个表达式的耦合系数为高斯TEM 00光束到这样的引导作为一个函数的引导和光束参数。
We have derived expressions for the field induced in a thin-film waveguide by plane waves incident upon an adjacent frustrated total reflecting interface. From these, we have deduced an expression for the coupling coefficient for a Gaussian TEM 00 beam into such a guide as a function of the guide and beam parameters.
