Dispersionless Manipulation of Reflected Acoustic Wavefront by Subwavelength Corrugated Surface
Free controls of optic/acoustic waves for bending, focusing or steering the energy of wavefronts are highly desirable in many practical scenarios. However, the dispersive nature of the existing metamaterials/metasurfaces for wavefront manipulation necessarily results in limited bandwidth. Here, we p...
