Modelling of CMUTs with anisotropic plates [PDF]

open access: yes2012 IEEE International Ultrasonics Symposium, 2012
Traditionally, CMUTs are modelled using the isotropic plate equation and this leads to deviations between analytical calculations and FEM simulations. In this paper, the deflection profile and material parameters are calculated using the anisotropic plate equation.
