I am trying to model a piezoelectric transducer. However I have a situation in which I am kinda confuse about. This deal with placing metal Aluminum electrodes on the top and bottom of PZT rods. Let me add the PZT rods are sourranded by polymer hexagonal tubes, there is a spave between the polymer and piezoelectric and this is vaccum all are being held together by epoxy. I just don't understand why there seems to be more oscillations in the resonance output when I used electrodes. I was expecting the fruquency shift to the left but not the oscillations. Any idea.
