Abstract In order to study total reflection tunnel effect of elastic wave in 1D square solid- liquid phononic crystal , Use the transition matrix method to calculate the transmissivity of elastic wave 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. Obtained the change rule of the properties of total reflection tunnel effect filtering with period and quantum number and side of square. Provided a theoretical basis for designing the good performance of phononic crystal filter.
