Broadband generation of accelerating polygon beams with large curvature ratio and small focused spot using all-dielectric metasurfaces

Broadband generation of accelerating polygon beams with large curvature ratio and small focused spot using all-dielectric metasurfaces

Self-accelerating polygon beams have drawn growing emphasis in optics owing to their exceptional characteristics of multiple self-accelerating channels and needle-like field distributions. Various approaches have been proposed to generate polygon beams, such as using spatial light modulators (SLMs)...
