Аннотация: The spectral properties of a one-dimensional phononic crystal bounded by a reflector in the form of an air layer are studied. A defect in a phononic crystal with a reflector at the edge results in coupling between the detect mode and acoustic Tamm state. This coupling between modes of different natures manifests as the hybridizatioПоказать полностьюn of modes, and the repulsion of dips in the reflectance spectrum is explained by avoided crossing of the modes.
