摘要：

A previously-published solution for the two-dimensional scattering of long waves by a parallel-walled duct, obtained by an informal application of the method of matched asymptotic expansions, is known to be incorrect. Here a formal procedure is used to obtain the correct solution. The power of the method is further illustrated by obtaining solutions for two other related two-dimensional problems which have no known exact solutions. The first is scattering by a rectangular inlet in an otherwise plane wall and the second is a variation on this problem with barriers projecting out from the inlet.
