Abstract

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 hybridization of modes, and the repulsion of dips in the reflectance spectrum is explained by avoided crossing of the modes.

一维声子晶体声学Tamm态和缺陷模的杂化

研究了以空气层为界的反射面为界的一维声子晶体的光谱特性。在声子晶体边缘有反射器的缺陷会导致探测模式和声学塔姆态之间的耦合。不同性质的模式之间的这种耦合表现为模式的杂化，而反射光谱中衰减的斥力可以用避免模式交叉来解释。
