Multifunctional wavefront-controlled metasurface for generating multiform quasi non-diffracting beams

Abstract: Multiform electromagnetic beams (multi-direction, multi-polarization, multi-frequency, and multi-beam) generated by ultrathin metasurfaces show promising prospects in multiple optical traps, modern communication systems, and identification in complex environments. However, their application is limited by their inability to generate desired multiform beams simultaneously. Here, a multifunctional surface using a polarization selection structure and integrated electric and magnetic structures is proposed to solve… Show more

“…In general, the complexity of the electromagnetic environment is mainly reflected in the multiscale characteristics of the computational region and the large frequency bandwidth of the excitation source. In the process of electromagnetic analysis, many target objects have multi-scale periodic/quasi-periodic characteristics, such as multiple-input multiple-output antenna [1,2], metamaterials surface [3,4] etc. Research on electromagnetic simulation algorithms of periodic arrays [5][6][7] with simple structures or small scale has achieved fruitful achievements.…”
