Self‐Assembling Cracks to Fabricate Antireflective Antifogging Metasurfaces

open access: yesAdvanced Optical Materials, EarlyView.
A multifunctional optical device combining antireflective and photothermal antifogging properties is developed by leveraging crack formation in colloidal films. Plasmonic nanoparticle arrays enable localized heating under illumination, while a mesoporous silica coating provides antireflection and water repellency.

Design of Double‐Sided Optical Coatings for Space Cooling Through Vertical Windows

open access: yesAdvanced Photonics Research, EarlyView.
Dual‐sided radiative cooling glass (DSRCG) utilizes the optical properties of epsilon‐near‐zero materials and ITO to exhibit directional emission toward the outdoor space, facilitating the heat dissipation of the glass, while exhibiting low emission toward the enclosure.

Optical Wireless Communications with Metasurfaces: Current Status and Potential for Intelligent Communications

open access: yesAdvanced Photonics Research, EarlyView.
Optical wireless communications (OWCs) provide a promising alternative to spectrum‐congested microwave wireless communications. Recently, the use of metasurfaces with sub‐wavelength features for dynamic beam steering, beam manipulation, and spatial or optical‐angular‐momentum mode generation, conversion, and multiplexing in OWCs is proposed and ...

Poka: A Necro‐Robot Beetle with a Measured Payload Ratio of 6847%

open access: yesAdvanced Robotics Research, EarlyView.
Here, Poka, a necro‐robot beetle with the ability to carry more than 68 times its own weight, is introduced, making it also a walking robot with the highest payload ratio measured to date. This paper is concerned with the design, manufacture and validation of ‘Poka', a novel millimetre‐scale necro‐robot aimed at bridging the performance gap between ...
