    Abstract

    We address the numeical prediction of anchor and interfacial dissipation in piezoelectric MEMS resonators with in-plane longitudinal-mode vibrations. Interfacial dissipation is formulated in terms of the stress jump across the interface. A refined dedicated numerical tool is employed both to evaluate anchor losses and to implement the model of interface dissipation. Extensive comparisons with experimental data are performed, showing excellent quantitative agreement.
