Continuous-phase-transformation acoustic metasurface
Acoustic metasurfaces are artificial structures, one of whose functions is to achieve plane wave focusing due to the phase gradient transformation of specific structural units. However, previous periodic acoustic metasurfaces for plane wave focusing have drawbacks such as discrete operating frequenc...
