Abstract
The technology described herein is directed towards a reconfigurable intelligent surface that receives and redirects incoming electromagnetic signals based on power efficient subarrays of unit cells. Each subarray integrates a power amplifier and tunable delay device to selectively amplify and delay the reflected signal. For example, the power amplifier and tunable delay device is shared by a m×n (e.g., 3×3) subarray of unit cells, which can be arranged as a module of a larger reconfigurable intelligent surface. Proper impedance matching between the power amplifier and the reconfigurable intelligent surface elements is maintained by using a matching circuit to minimize signal reflection. The system design thus provides a device for receiving and reflecting the electromagnetic signal in the same polarization by coupling the RF energy, processing, amplifying, and adding delay to mitigate any interference. The technology facilitates estimation of the angle of arrival of the incoming signal.
