AI Technical Summary
Existing technologies struggle to achieve flexible geometric phase control on dynamic metasurfaces, and traditional methods require a massive amount of parameter traversal work and mechanical movement, limiting the application of dynamic metasurfaces.
By employing a heterogeneous integrated terahertz metasurface, and combining a bilayer split ring structure of gold and tunable vanadium oxide, along with holographic algorithms and global heating technology, a dynamically tunable geometric phase is achieved, avoiding parameter traversal and mechanical movement.
It achieves pixel-level optical field complex amplitude modulation, with fast modulation speed and easy execution, and is suitable for dynamic display, projection, temperature-changing optical encryption and anti-counterfeiting fields. The structural design also supports fine phase distribution.
