Programmable Chiral Radiation via Spin‐Decoupled Metasurface with Integrated Compound Phases

Advanced Science, Volume 13, Issue 1, 5 January 2026.
A programmable spin‐decoupled metasurface integrating propagation and geometric phases enables high‐purity chiral radiation with reconfigurable emission direction. Spin‐selective radiators combined with a compound phase decoupling strategy suppress undesired components, while embedded PIN diodes allow real‐time directional control.
