Ultrasound transduce output

Please login with a confirmed email address before reporting spam

I like to model an ultrasound transducer as shown in the attached figure. I have all material properties from the manufacturer. I want to have 4 highlighted part in my Comsol model.

-For the backing part, only impedance is given. Is there any way that I can implement the backing as an impedance boundary on the back of the active element.
-For wear plate (which is a solid material), I have added it to the pressure acoustic and not solid mechanics physics. Is this a correct thing to do? I am not interested in stress / strain of wear plate. I just want to make sure that it correctly transmit the ultrasound waves.

Is there anything that needs to be fixed in the model?

I could not attach the file. Instead, I have shared dropbox link. Sorry for the inconvenience.

I appreciate your help in advance.

Thanks,
