Nobody comes here and admits that they must DESIGN a circuit for college. They are simply asking for an existing circuit they can copy. They are not even looking for the circuit.
Most circuits on the web are low power ultrasonic pest repellers.
An ultrasonic cleaner is not very popular so the high power transducer is probably custom-made. You might not find a detailed datasheet for one.
The circuit in post #5 uses two 9V batteries. Instead if they are a +9V and +18V power supply then the output will be 36V peak-to-peak.
What is "a single wave transducer"?
