Abstract With the ability to focus and rotate the acoustic field in a given region while keeping the outside region unchanged. the acoustic concentrator and rotator has been developed for the versatile manipulations of acoustic wave. In this letter. we report the design of acoustic concentrator and rotator facilitated by linear coordinate transformation. https://www.bekindtopets.com/quick-grab-Canine-Spectra-KC-3-Single-Dose-great-price/
