Title: Total Reflection Tunnel Effect and Filtering Characteristics of Flat Panel Phononic Crystal
Abstract: For studying total reflection tunnel effect of elastic wave in 1D flat panel phononic crystal,the transition matrix method is adopted and the transmissivity of elastic wave is studied when incident angle greater than full reflection angle.Total reflection tunnel effect is found in the transmission wave and there is a good multi-channel filtering characteristics.Response curves of the tunnel effect versus period is obtained and response curves of the tunnel effect versus quantum number of mode and response curves of the tunnel effect versus thickness of flat panel is obtained.They are theoretical basis for designing the high-quality filter of phononic crystal.
