Digital phase shifters have been applied in traditional phased array antennas to realize
beam steering. However, the phase shifter deals with the phase of the induced current; …

We numerically study the optical properties of metal-insulator-metal resonators and
metasurfaces, emphasizing the presence of gap-surface plasmon (GSP) resonances and …

We study the possibility of analytically synthesizing different polarization-transforming
devices realized as arrays of small particles. The proposed method is based on general …

This study reports a gallium-based thermal interface material (GBTIM) consisting of gallium
oxides dispersed uniformly into the 99% gallium metal. The wettability of GBTIM with other …

Gradient metasurfaces (GMs) can provide pre-defined wave vectors that are along the
surface of GMs. When the additional wave vector is greater than that of incident waves, the …

The systematic design of unit cells for a Huygens metasurface, a particular class of
metasurface, is presented here. The design of these unit cells uses transmission-line theory …

This tutorial aims to provide an extensive overview of methods of generating and shaping
light at new frequencies by using nonlinear metasurfaces. We first review methods of …

Optical metasurfaces patterned arrays of plasmonic nanoantennas that enable the precise
manipulation of light–matter interactions are emerging as critical components in many …

High refractive index makes silicon the optimal platform for dielectric metasurfaces capable
of versatile control of light. Among various silicon modifications, its monocrystalline form has …

Realizing the arbitrary manipulation of light intensity on the microscale is a fundamental
requirement for the miniaturization and integration of optical devices, which would have a …
