5. Models of volume wave devices on thin films

As with surface waves, models specifically dedicated to volume wave resonators, and in particular those developed using piezoelectric thin films for high-frequency filtering, can be classified in ascending order of complexity. We propose here a presentation according to this order, starting with a simple but highly efficient one-dimensional model and ending with numerical methods combining finite elements and boundary integrals.

5.1 Mason's model

The principle of Mason's model, which has been published countless times but whose basic reference remains
