I am trying to create a set-up where I can radially vibrate a 1x1 cm sample using a piezoelectric disc transducer. I know that at the $f_{min}$ of a PZT transducer, for the disc geometry, there is a radial vibration. How can I tune this vibration if I want to vibrate my sample radially at different frequencies?

$\begingroup$ Sorry for my ignorance on this topic,but what is the sample made out of. It is metal. Also you might want to look at this link too. engineering.stackexchange.com/questions/2695/… $\endgroup$ – Mahendra Gunawardena Jun 18 '15 at 0:50
