Absorbing layer in "Piezoelectric devices"

I'm simulating a SAW device with an IDT on top of a slab of ZnO. As seen in the picture, bulk waves are launched as well. What boundary conditions should I have at the bottom if I don't want to have reflections of the bulk waves? It seems that "Perfectly matched layer" should do it, but I don't see that in my options. I only have "Piezoelectric device" physics loaded, do I need to load the whole acoustics module as well?

Also, at the left boundary I have symmetric boundary conditions to effectively show half of the device. Makes sense?
