A Shear-Wave Microprobe Utilizing Surface-Wave Mode Conversion
A very small aperture ultrasonic probe for detecting shear waves was desired for ultrasonic shear-wave field mapping [1–3]. Several designs of such a probe were developed and evaluated. During the course of probe development, a very interesting phenomenon was observed and was used to build an improved shear-wave microprobe that is unique in design and capability. This report describes design evolution, advantages, and applications of this new probe.
