摘 要：A simple planar multilayer structure was proposed for the observation of acoustic Tamm states.The theoretical and experimental studies show that acoustic Tamm states can be formed at the interface between double one-dimensional phononic crystals with extremely narrow cavity between them.When the width of the cavity increases,the acoustic Tamm states gradually disappear and the cavity resonant states appear instead.By studying the field distribution,we give the physical explanation for the two different acoustic interface states.
