Abstract
A scalable reconfigurable intelligent surface (RIS) includes a plurality of RIS elements. The RIS elements include: a radio frequency identification (RFID) chip that powers the RIS element; a RFID antenna connected to the RFID chip; a RIS variable impedance controlled by the RFID chip; and a RIS antenna connected to the RIS variable impedance. The plurality of RIS elements produces a reflection beam that may be directed to a specific location. The RFID chip receives steering information to steer the reflection beam.
