On the non-existence of trapped modes in acoustic wave-guides

It is well known that trapped modes exist in certain types of acoustic waveguides. These modes correspond to localized fluid oscillations and occur at frequencies at which propagating modes down the guide are not able to exist, below a so-called ‘cut-off frequency’. For example, antisymmetric trappe...
