Abstract

Inversion Layer Transducers (ILT) have attracted considerable interest in the recent past, due to the wide bandwidth and even harmonic sensitivity. This paper presents a new three-port lattice model for ILT devices. Based on linear systems theory, a discrete bi-directional lattice is used to describe the mechanical wave propagation and continuous transfer function to represent the electrical parameter. The mathematical formulation for an ILT configuration, and a straightforward physical interpretation of the lattice model is presented. A selection of experimental and simulation results are included to demonstrate the feasibility of the technique
