Multipolar Resonances in Electro‐Optic Metasurfaces with Moderate Refractive Index
Electro‐optic nanoantennas with moderate refractive indices of 2.3 to 3.0 are numerically shown to sustain strong multipolar resonances, enabling efficient light confinement and EO tuning. Multipolar modes of even parity are most sensitive to variations in the refractive index.

Curvy Surface Reconstruction. [PDF]
This review introduces the concept of “general curvy surface reconstruction,” which incorporates both geometric and physical dimensions, representing an upgrade over conventional geometric reconstruction that focuses solely on spatial relationships. Particular emphasis is placed on the emerging opportunities enabled by advanced measurement techniques ...

This work provides a multifunctional programmable transmissive metasurface with phase and amplitude manipulation capability in the sub‐6G band. By applying different coding strategies, the proposed metasurface can realize vortex beam generation, holographic imaging under phase coding mode, and multi‐beam forming in phase‐amplitude joint coding mode ...

Compressive Holographic Video [PDF]
Compressed sensing has been discussed separately in spatial and temporal domains. Compressive holography has been introduced as a method that allows 3D tomographic reconstruction at different depths from a single 2D image.

Diffraction from deformed volume holograms: perturbation theory approach [PDF]
We derive the response of a volume grating to arbitrary small deformations, using a perturbative approach. This result is of interest for two applications: (a) when a deformation is undesirable and one seeks to minimize the diffracted field's sensitivity
