Resumo
The spectral properties of a one-dimensional phonon crystal bounded by a reflector in the form of an air layer are studied. The presence of a defect in a phonon crystal with a reflector at the edge leads to a connection between the defective mode and the acoustic Tamm state. This connection of modes of different nature manifests itself in the form of hybridization of modes, and the pushing apart of dips in the reflection spectrum is explained by avoided crossing of modes.
