Metasurface-based attacks could let hackers intercept wireless interactions

Metamaterial interface waveguides can confine and guide electromagnetic (EM) waves, which has attractive potential in integrated photonics physics and wireless devices, from radio frequencies to o ...

In the daily lives of humans, the manipulation of electromagnetic waves and information has turned out to be vital. Intelligent metasurfaces have topped as smart platforms for regulating the wave–information–matter interactions in the absence of manual intervention.

Metasurfaces are artificial array structures consisting of subwavelength unit cells arranged on a specific two-dimensional surface. Dynamic, reconfigurable metasurfaces are an excellent way to manipulate electromagnetic (EM) waves flexibly.
