摘要

为了有效地激励会聚多模动态涡旋光束，提出了一种可重构的1位数字编码超表面。引入的超表面由可重构单元组成，通过集成PIN二极管来调制单元的反射相位特性，实现1位相位量化。通过编程实现了超表面的相位分布。，动态涡旋光束因此受到刺激。

Programmble Metasurface for Efficient Generation of Convergent Multi-Mode OAM Beams

A reconfigurable 1-bit digital coding metasurface is introduced for efficiently stimulating convergent multi-mode dynamic vortex beams. The introduced metasurface consists of reconfigurable cells with 1-bit phase quantization by integrating the PIN diode to modulate the reflective phase property of the cell. Through programming the phase distribution of the metasurface., the dynamic vortex beams are thus stimulated.
