TL;DR: This work demonstrates a general platform for design of dual magnetic resonance based meta-holograms based on the geometric phase using silicon nanostructures that are quarter wavelength thick for visible light and can be unambiguously observed without a receiving screen even under the illumination of natural light.

TL;DR: In this article, the authors examine how novel nanophotonic platforms could overcome the hardware restrictions of existing LiDAR technologies and present the device specifications required by the industrial sector.

TL;DR: This Perspective focuses on metasurface holograms and colorations for projective and reflective display techniques and briefly introduces the working mechanism and reviews state-of-the-art techniques in each field from perspective of materials, functionalities, and fabrication methodologies toward real-life display applications.

TL;DR: In this article, a compact sensor platform that integrates liquid crystals and holographic metasurfaces is proposed to autonomously sense the existence of a volatile gas and provide an immediate visual holographic alarm.

TL;DR: In this article, a bifunctional metasurface which combines both structural color printing and vectorial holography with eight polarization channels was proposed for advanced encryption applications.
