Im doing a SAW resonator, and Im interested in seeing the wave response thanks to a voltage excitation but also seeing the voltage response thanks to a reflected surface wave.
I manage to generate the wave with a gaussian pulse modulated in the resonator central frequency, and I define all electrode faces with the same potential representing it as a metal electrode and not just as an elastic electrode. The problem is that when I fix the voltage with Terminal or with Electric Potential I cant see the voltage generated by the surface wave reflections.
Is there a way to define an Electrical Potential that responds to the equations from a piezoelectric model and applies the voltage neeeded for the wave, or simply a way of deactivating the source after the pulse has been applied so the electrodes can react to the voltage from the wave?
