Experimental data of the sole Bragg reflector is difficult to be measured. This is because the property of a piezoelectric layer on Bragg reflector and that of the sole Bragg reflector is measured simultaneously in the standard impedance measurement. In this study, the method to evaluate the acoustic transmission loss for longitudinal wave and shear wave of the sole Bragg reflector by using pulse echo technique with SiO2 delay line is proposed. |
