Abstract
This paper presents an accurate method to calculate the P-matrix of an arbitrary transducer on an arbitrary substrate material. The approach is based on the COM model, and COM-parameters (transduction, reflectivity, capacitance and velocity) are calculated for each individual cell of the transducer in a way such that the influence of the neighboring cells is taken into account. Very good agreement between modelled and measured data is shown which verifies the approach.
