Reconfigurable Intelligent Surfaces (RISs) are a class of artificial structures that can manipulate wireless signals to modify the propagation environment, composed of sub-wavelength scatterers ...
Abstract: Active reconfigurable intelligent surfaces (RISs) have recently been proposed to complement and generalize passive RIS. In this work, the design for an active RIS based on ...
The polyfill emulates flex gap by adding margins to each child element and applying a negative margin to the container.
