Workload Characterization of Programmable Metasurfaces [PDF]

Proceedings of the Sixth Annual ACM International Conference on Nanoscale Computing and Communication, 2019
Metasurfaces are envisaged to play a key role in next-generation wireless systems due to their powerful control over electromagnetic waves. The last decade has witnessed huge advances in this regard, shifting from static to programmable metasurfaces. The HyperSurface (HSF) paradigm takes one step further by integrating a network of controllers within ...

Programmable polariton canalization in reconfigurable metasurfaces. [PDF]

Sci Adv
The topological transition of polariton dispersion in twisted van der Waals layers at the photonic magic angle results in the diffraction-less and collimated propagation state, termed canalization regime. This type of robust transport of polaritons (i.e., polariton canalization) holds promise for subwavelength control of energy flows. However, the lack

Time-Modulated Transmissive Programmable Metasurface for Low Sidelobe Beam Scanning [PDF]

Research, 2022
Programmable metasurfaces have great potential for the implementation of low-complexity and low-cost phased arrays. Due to the difficulty of multiple-bit phase control, conventional programmable metasurfaces suffer a relatively high sidelobe level (SLL).
