Multifunctional tunable terahertz metasurface with 20 independent channels and ultra-low crosstalk via bidirectional full-polarization decoupling and frequency multiplexing

Boosting channel density represents a core demand for terahertz (THz) metasurfaces deployed in next-generation information processing systems. However, the dense integration of multiple functions often leads to severe inter-channel crosstalk, which remains a critical bottleneck in this field. Here, we design a compact...
