WebJan 9, 2024 · Two different operating regimes of IRSs can be distinguished: 1. Both transmitter and receiver are in the far-field of the surface. Then the waves seen at the surface can be approximated as planar; the phase differential from the surface center to its edge is less than a few degrees, say. In this case the phase shifts applied to each atom ... WebNov 23, 2024 · The intelligent surfaces, as the name suggests, possess reconfigurable reflection, refraction, and absorption properties with regard to electromagnetic waves. “We are doing a lot of fundamental research. The idea is really to push the limits and the main idea is to look at future networks,” Di Renzo said.
WebApr 1, 2024 · Particularly for the reflection, for regular surfaces of a medium, the angle of incidence is the same as the angle of reflection, as shown in Fig. 1 (a). Recent research advances on reflectarrays with metasurfaces have enabled changing the impedance of the surface and achieving a certain phase shift between the incident and scattered waves [ 19 ].
