Abstract
The technology described herein is directed towards a design and implementation of a subarray of unit cells for an active reconfigurable intelligent surface that is power efficient. The reconfigurable intelligent surface design integrates a switch and a power amplifier in subarrays of unit cells to selectively amplify the reflected signal, resulting in a selectively active reconfigurable intelligent surface with relatively low power consumption. Further, rather than equipping each unit cell with its own switch and power amplifier, a switch and power amplifier is shared by each m×n (e.g., 3×3) subarray of unit cells, which can be arranged as a module of a larger reconfigurable intelligent surface. Via the switch, the design provides a device for receiving and reflecting the electromagnetic signal as an amplified or non-amplified signal by coupling the RF energy, processing, and selectively amplifying or not amplifying the reflected signal.
