Very usefull for me. I still learn piezo. God job.

Thanks for the comment! Please let me know what else you would like to learn!

Super useful video for understanding the basics, thanks a ton! Do you know if it's possible to simulate the k2 accurately in comsol, like would it show itself in the output current freq domain plot?

[@ultrasonicadvisors]

Of course! However, experimental factors will typically cause the measure k2 to be lower than your simulation. Simulation is perfect and experimental are real. No such thing as "real perfect."
