These data represent capillary waves, where each frame contains a wave surface in two-dimensional space. We placed 40uL of liquid on a lithium niobate (piezoelectric) thickness-mode transducer within a 3/8" circular boundary formed by a single layer of polyimide tape. Then we applied a sinusoidal voltage signal to the transducer and recorded holograms of an approximately 300um x 300um field of view using a digital holographic microscope (LynceeTec) coupled with an ultra-high-speed camera (Photron) operating at 115,200 frames per second. The driving frequency of the signal was set to the resonance of the transducer (6.905 MHz). We varied the amplitude of the input signal, resulting in different transducer particle velocities and corresponding acoustic capillary numbers. Each dataset represents a liquid type and acoustic capillary number, with repeated experiments under identical conditions. We provide the data in HDF5 formats, containing the full wave field over time, as well as the comma-separated value files that contain the time series of the central pixel (i.e., the center point of the spatial domain).
