Metasurfaces, the ultrathin, 2D version of metamaterials, have recently attracted a surge of
attention for their capability to manipulate electromagnetic waves. Recent advances in …

We review the basic physics and applications of a special class of planar metamaterials,
often called metasurfaces, which are composed of optically thin and densely packed planar …

Here, we first aim to explain practical considerations to design and implement a
reconfigurable intelligent surface (RIS) in the sub-6 GHz band and then, to demonstrate its …

Metasurfaces, two-dimensional equivalents of metamaterials, are engineered surfaces
consisting of deep subwavelength features that have full control of the electromagnetic …
