Although recent progress in metasurfaces has shown great promise for applications, optical properties in metasurfaces are typically fixed by their structural geometry and dimensions. Here, an electrically controllable amplitude of anomalously‐refract... Read More about Amplitude Modulation of Anomalously Refracted Terahertz Waves with Gated-Graphene Metasurfaces.

Octave-Spanning Broadband Absorption of Terahertz Light Using Metasurface Fractal-Cross Absorbers (2017)
Journal Article

Synthetic fractals inherently carry spatially encoded frequency information that renders them as an ideal candidate for broadband optical structures. Nowhere is this more true than in the terahertz (THz) band where there is a lack of naturally occurr...
