Abstract
A method of and system for producing a Bessel-like collimated sound beam frequencies below 1 MHz, and a device for sound (acoustic) imaging. A flat disk piezoelectric transducer having a large diameter/thickness ratio may be configured to exhibit radial vibration modes in the desired frequency range according to one or more parameters, including the diameter/thickness ratio, materials, electrode coverage, etc. The transducer may be driven by a waveform generator at one or more radial mode excitation frequencies.
