Generation of diffraction-free beams using resonant metasurfaces

Generation of diffraction-free beams using resonant metasurfaces

Several metasurface diffraction-free beam generators are designed by using a set of resonant V-shaped nanoholes. Cosine beams, Bessel beams and cosine Bessel beams are generated through the corresponding metasurface structures with V-shaped nanoholes arranged in different ways. Theoretical analysis...
