Abstract
Acoustic Coding Metasurfaces In article number 2308349, Hao-Wen Dong and co-workers employ topology optimization techniques to design a 3-bit broadband acoustic coding metasurface. With the 3-bit coding units, a broadband acoustic vortex metasurface is established. Within the target frequency domain, it can modulate reflected acoustic waves into vortex waves. Combined with convolution methods, we outline the approach to constructing an acoustic vortex beam deflection metasurface.
