Abstract :
By taking the spatial distribution of the dissipated power into account the modeling of Bulk Acoustic Wave Resonators at higher power levels could be improved. The simulation results have been verified by measurements of vectorial scattering parameters during high power loads and by measurements of the temperature increase due to the self-heating by infrared thermography.
