Rayleigh angle incident ultrasonic beam shape design influence on reflected beam

Current evolutions in transducer design, such as phased arrays, but more importantly, metamaterials-based acoustic lenses, potentially enable generating specific beam shapes earlier unconsidered. It is known that the Schoch effect, when a bounded incident on submerged solid reflects at Rayleigh angle, depends width and frequency. This work numerically explores consequence of shape beams effect invites further experimental work. The study investigates square with exponential flanks compared to Gaussian reference profiles incorporates diffraction upon sound propagation resemble reality better. shown stunning differences occur depending shape, particularly for beams.
