Hi all,
I am investigating reflections of surface acoustic waves on piezoelectric materials. Initially, I thought I would use the free boundary condition as it seemed to be reflecting the wave back. However, I just wanted to make sure if there is a more sophisticated way of achieving this. Cheers, Alp

Surface waves will be reflected- to a degree- by any discontinuity. A free surface will be a fairly efficient reflector. However there will be mode conversion. Look for reflected transverse, longitudinal, or plate waves depending on your circumstance.

Hi, Alperen,
I also need to consider the wave reflection in my research. The wave reflection is inevitable in practical situation and I think a free surface will be better. However, in order to obtain more reliable simulation results compared with the experimental tests, the characteristics of the sensor and circuits should be included in the model. I am doing this part now but have not got good results yet.
