Jam frequency -- 2

Jammer frequency PZT ultrasound transducers (d = 35 mm) having a single quarter-wave matching layer, a center frequency of [url removed, login to view] MHz, and a −6 dB fractional bandwidth of 65% with two peaks ([url removed, login to view] MHz, [url removed, login to view] MHz). LILFU waveforms used as stimuli were generated by repeating pulse trains of US tone bursts at a pulse repetition frequency until a desired number of tone bursts had been generated (Figure 1B). Ultrasound tone bursts were generated by trains of square waves (0.2 µsec) with variable amplitudes (Table S1) using an Agilent 33220A function generator. To produce final plate voltages delivered to transducers, square waves were further amplified (50 dB gain) using an ENI 240L RF amplifier. Square waves were delivered between [url removed, login to view]–[url removed, login to view] MHz depending on the acoustic frequency desired, while the number of square waves driving each US tone burst equaled the number of acoustic cycles desired for a given US tone burst. Each US tone burst (pulse) contained between 1 and 50,000 acoustic cycles depending on the LILFU waveform generated. US tone bursts (Figure 1B) were repeated at a pulse repetition frequency by triggering the above referenced function generator with a second Agilent 33220A function generator. Pulse repetition frequencies were either a constant frequency or a swept waveform. Our primary LILFU waveform (LILFU-1) had the following properties: f = [url removed, login to view] MHz, TBD = 22.7 µs, c/tb = 10, PRF = 5 sec sweep 0–100 Hz, and Nt
