Intelligent Metasurfaces with Continuously Tunable Local Surface Impedance for Multiple Reconfigurable Functions
Intelligent Metasurfaces with Continuously Tunable Local Surface Impedance for Multiple Reconfigurable Functions
How might one make metasurfaces ``intelligent'', to offer multiple reconfigurable functions? The authors show that it can be done by embedding individually addressable tunable chips (mixed-signal integrated circuits) in each unit cell. This enables independent, continuous control of both the resistive and reactive parts of the local complex surface impedance. …
