Frequency-dependent beam steering by a focusing array of surface acoustic wave transducers: experiment

Experimental results that verify focusing and dispersion with frequency of surface acoustic waves (SAW) by wide-band phased array of SAW interdigital transducers (IDTs) are presented. The diffraction sidelobes are suppressed by weighting the drive to each IDT using capacitive taps.
