| Abstract: | The problems of existence of eigenoscillations in infinite cylindrical regions comprising a thin cylindrical obstacle are
studied. The existence criteria for eigenoscillations are obtained. For obstacles allowing axial symmetry, the dependence
of eigenoscillation frequencies on the obstacle dimensions is studied. The form of eigenoscillations is studied for the first
modes.
