Raw data for 'Control of High-Frequency Surface Acoustic Waves via Transducer Geometry and Higher-Order Mode Equivalency'

The data are uploaded into 3 folders. The folder named 'Figure__data' contains the dataset for the figures in the manuscript. The second (named 'Constant_P_1000nm') and third (named 'Constant_DC_25_and_others') folders contain the raw data for constant P = 1000 nm and constant duty cycle of 25% (and additional duty cycles), respectively.

Folder 1: contains 4 subfolders for Figures 1-4 in the manuscript.
