Title:
ASYMMETRIC ACOUSTIC WAVE SEPARATOR BASED ON BINARY METASURFACE
Document Type and Number:
WIPO Patent Application WO/2023/216507
Kind Code:
A1
Abstract:
An asymmetric acoustic wave separator based on a binary metasurface. The separator comprises a first supercell (10) and a second supercell (20) arranged opposite each other, wherein the first supercell (10) has a first acoustic metasurface; the second supercell (20) has a second acoustic metasurface; there is an air gap Δd between the first supercell (10) and the second supercell (20); the first supercell (10) comprises several first cells (11) and several second cells (12), which are alternately arranged; the second supercell (20) comprises several third cells (21) and several fourth cells (22), which are alternately arranged; the third cells comprise two groups of first cells (11); the fourth cells comprise two groups of second cells (12); the phase difference between each first cell (11) and each second cell (12) is π; and the phase difference between each third cell (21) and each fourth cell (22) is π.
