Abstract: The method of changing ultrasound wave frequency by using the acoustic matching layer presents a replaceable acoustic matching layer to offer an effective means of filtering the original broadband frequency of an ultrasonic transducer into certain composite discontinuous frequencies. The filtering effect could be improved by connecting the electrodes of the acoustic matching layer when it is made of a poled piezoelectric material. This method may provide novel applications for commercial ultrasonic transducers.
