Because our device operates across a broad-spectrum frequency range that includes both kHz and MHz frequencies, we use two different electronic set-ups to create and control the electronic sine waveforms applied to the embedded IDTs. In the range of 1-30 kHz, we create the sine waveform using an Arbitrary Function Generator (AFG 31000, Tektronix, Germany) across a range of applied peak-to-peak power that is then amplified by factor of 100 using a High Voltage Amplifier (TREK Model 2210, Acal BFi, Germany). In the MHz range, we create the sine waveform using an Arbitrary Function Generator (AFG1062, Tektronix, Germany) with the same range of applied peak-to-peak power, amplified by a custom-built amplifier comprising a Mini-Circuits Model ZHL-32A+ op-amp powered by an RS-PRO RS-3005D Digital Control DC Power Supply. All electronic connections are established using standard BNC cords, connectors, and test clip adapters from Thorlabs Inc.
