All‐Dielectric Programmable Huygens' Metasurfaces [PDF]

Advanced Functional Materials, 2020
AbstractLow‐loss nanostructured dielectric metasurfaces have emerged as a breakthrough platform for ultrathin optics and cutting‐edge photonic applications, including beam shaping, focusing, and holography. However, the static nature of their constituent materials has traditionally limited them to fixed functionalities.

Programmable Acoustic Metasurfaces [PDF]

Advanced Functional Materials, 2019
AbstractMetasurfaces open up unprecedented potential for wave engineering using subwavelength sheets. However, a severe limitation of current acoustic metasurfaces is their poor reconfigurability to achieve distinct functions on demand. Here a programmable acoustic metasurface that contains an array of tunable subwavelength unit cells to break the ...

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 ...

An Optically-Programmable Absorbing Metasurface [PDF]

2018 IEEE International Symposium on Circuits and Systems (ISCAS), 2018
A tunable metasurface absorber is presented in this work using an optically-programmable capacitor as the tuning element. The tuning element does not employ conventional semiconductor technologies to operate but rather a bases its tuning by changing the optomechanical properties of its dielectric, poly disperse red 1 acrylate (PDR1A).
