Hello Sir Yes, I have substrate also in CMUT so It might affect. right? I would like to check the effect on the membrane or on the substrate.
Two membranes are there, one is fixed which is substate and another one is movable.
My task is to check whether Lamb, Scholte, Rayleigh or stonely wave present or not.

Is there any tutorial available regarding this?
Thanks and Regarding Dhruvin
