AI Technical Summary
Existing orbital angular momentum metasurfaces have shortcomings in terms of transparency, broadband, multi-beam, and high transmission efficiency, making it difficult to achieve stable electromagnetic control and optical transparency in transparent communication scenarios, and they also have high processing complexity.
By combining a transparent glass substrate with an indium tin oxide transparent conductive film, an orthogonal transparent grating layer, a square frame structure, and a modified I-shaped resonant unit are designed. Through their synergistic effect, a broadband multi-beam orbital angular momentum transmission metasurface is realized. The phase is controlled by the rotation angle of the modified I-shaped resonant unit. Combined with feed phase compensation and orbital angular momentum spiral phase superposition, a two-dimensional array is formed.
It achieves broadband, high-efficiency, multi-beam orbital angular momentum electromagnetic wave radiation on a transparent platform, taking into account both optical transparency and electromagnetic control, reducing processing complexity, and is suitable for smart windows and transparent communication terminals.
