我们考虑一个近似的解决方案的基础上匹配的渐近展开的问题的波散射的任意数量的窄通道延伸垂直于两个直的平行壁之一，定义了一个均匀的波导。匹配过程导致方程组，其大小等于侧通道的数量。特别强调的是放在理解的效果，通道共振入射波的反射中发挥。
We consider an approximate solution based on matched asymptotic expansions to the problem of wave scattering by any number of narrow channels extending perpendicularly to one of the two straight parallel walls defining a uniform waveguide. The matching process results in a system of equations whose size equates to the number of side channels. Particular emphasis is placed on understanding the effect that channel resonance plays in the reflection of incident waves.
