Abstract

In this paper, we present an extension of an acoustic transmission-line model for PMUT–horn systems that enables the prediction of acoustic pressure using a Rayleigh far-field formulation. The approach is validated against finite element method (FEM) simulations, showing consistent prediction of radiation directivity at 200 kHz. The model provides a computationally efficient alternative to FEM simulations for the design of horn-assisted PMUT systems.
