State of the Art of Low‐Frequency Acoustic Modulation: Intensity Enhancement and Directional Control
High intensity low‐frequency sound sources hold significant value in many fields. However, their long wavelength, strong penetrability, and tendency to diffract make direction control and intensity enhancement challenging. Acoustic generators and metamaterial‐based acoustic devices still face issues such as low energy efficiency, poor directional ...

Three‐Channel Wavefront Shaping Using Non‐Interleaved Spin‐Multiplexed Plasmonic Metasurfaces
A versatile non‐interleaved plasmonic metasurface platform has been developed using quarter‐wave plate meta‐atoms for independent and simultaneous phase modulation of both co‐ and cross‐polarized circularly polarized waves. Three proof‐of‐concept designs have been validated in the near‐infrared: a beam deflector with three distinct reflection angles, a

Natural Crystal Structure for Generating Raman‐Like Orbital Angular Momentum States
This work proposes a strategy for symmetry breaking of the degenerate OAM states relying on the natural anisotropy of crystal gain, to select the handedness of the spatial spiral phase front and further tunable Raman‐like OAM states by thermal‐driven, which clarifies the contribution of intrinsic crystal property to the OAM states and opens a new route
