Abstract：For studying total reflection through effect of elastic wave in 1D phononic crystal , the transition matrix method is adopted and the transmissivity of elastic is studied when incident angle greater than full reflection angle. Two transmission peaks are found in the transmission wave, it is total reflection through effect . Response curves of the through effect versus incident angle is obtained and response curves of the through effect versus medium thickness is obtained and response curves of the through effect versus cycle number is obtained. Total reflection through effect of elastic wave in 1D phononic crystal is explained with the theory of quantum and the theory of evanescent wave.
