## Communicated by F. Ursell This article establishes the existence of trapped-mode solutions of a linearized water-wave problem. The fluid occupies a symmetric horizontal channel that is uniform everywhere apart from a confined region which either contains a thin vertical plate spanning the depth
Cutoff frequencies in waveguides of external circular shape and an inner square boundary are determined by means of conformal mapping and a variational technique. The algorithmic procedure is quite straightforward, accurate and applicable to any doubly connected region provided that the mapping func
