Hello!
I has trying to simulate SAW (Surface Acoustic Wave). How can i get insertion loss ?
Thank for any help!

Are you working with SAW sensor?. In comsol you can get the admitance and using S11 = (ZL - Z0)/(ZL+Z0) taking Z0 for example as 50 Ohm you can get the return loss. I dont know if you can use a similar process for the S21 (insertion loss)

Hi,
I am a student from China ,working on the simulation of SAW device. And I also want to get the insertion loss, you know, it is very important to the device. But I am really new at COMSOL, I don't know how to get it. Have you got the insertion loss? If you know how to get it now, please help me solve this problem.Thank you in advance!

Best regards!
