All‐Dielectric Programmable Huygens' Metasurfaces [PDF]

open access: yesAdvanced 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.

Surface Impedance Modeling of All-Dielectric Metasurfaces [PDF]

open access: yesIEEE Transactions on Antennas and Propagation, 2020
We develop a simple and reliable analytical model that allows describing the electromagnetic response of all-dielectric metasurfaces consisting of a single-layer array of high-permittivity spherical particles. By combining Mie theory with a bi-dimensional homogenization approach, we derive closed-form expressions of the electric and magnetic surface ...
