Abstract
A method of fabricating a binary metasurface for producing an ultrasound Airy beam for underwater ultrasound applications is provided. The method includes generating an amplitude distribution of an Airy beam at a frequency, and converting the amplitude distribution into a binary phase profile. The method also includes generating a 3D printing design of a binary metasurface based on the binary phase profile, wherein the binary metasurface includes ridges and grooves defined by neighboring ridges, a ridge having a thickness corresponding to a phase delay of π/2 of the Airy beam between water and a 3D-printable material. The method further includes additively manufacturing the binary metasurface with the 3D-printable material based on the 3D printing design.
