Abstract	A new method of formulating the core matrix of a transducer model is presented that is in the form of a translation matrix, enabling us to easily model any arbitrary collection of a group of transducers and/or acoustic loads. The validity of this formulation have been verified by performing measurements on an stack of 3 piezoceramics with different interconnection configurations. Based on the idea of phase accumulation, low frequency piezoelectric transducers have been realized using thin, high frequency piezoelectric ceramics. Compared to conventional methods (increasing the transducer bandwidth by damping), this method has proven to be superior in increasing the conversion efficiency of the transducer. In addition, there is no need for using thick piezoceramics and this is an important advantage, considering the difficulty in poling and processing of thick piezoceramics.
