Directional Light Scattering In Mie‐Resonant Si Particles With Ultra‐Thin Au Shells

open access: yesAdvanced Optical Materials, EarlyView.
Si@Au core‐shell particles have been produced to study their ability to directionally scatter light. We found that the heavily reported particulate shells do not overlap the electric and magnetic dipoles well, where continuous shells have better overlap. Experimental analyses, including nanomaterial characterization, EELS and single‐particle dark‐field

A Near Infrared Emission Feature from Visible Fluorescence Tails and its Correlation with Singlet Oxygen

open access: yesAdvanced Optical Materials, EarlyView.
A persistant NIR emission tail and feature at 923 nm is observed during photochemical singlet oxygen generation using various photosensitizers. While initially considered as singlet oxygen phosphorescence we show that it arises from the NIR‐tail of (visible) photosensitizer emission and the non‐linear increase of detector sensitivity.

Tunable Multifunctional Terahertz Coding Metasurface for Polarization Manipulation

open access: yesAdvanced Photonics Research, EarlyView.
Coding metasurfaces (CMs) offer versatile control over electromagnetic waves. Herein, a tunable multifunctional terahertz (THz) metasurface integrated with vanadium dioxide (VO2) is presented, enabling propagation‐phase manipulation of linearly polarized waves and hybrid‐phase control of circularly polarized waves.

Synthesis of Self‐Healing Microbeam by Superposition of Self‐Decelerating Corner‐Diffraction Beams

open access: yesAdvanced Photonics Research, EarlyView.
Quasi‐nondiffracting (QND) beams boast long‐range propagation and self‐healing capabilities but require complex beam‐forming platforms. In contrast, the photonic nanojets (PNJs) boast simple platforms but are utilized primarily for near‐field applications. This work aims to hybridize the QND and PNJ beam concepts with a view to realize microscale, self‐

Integration of Soft‐Robotics and Deep Learning to Assess the Coordinated Biosonar Emission and Reception Dynamics in Hipposiderid Bats

open access: yesAdvanced Robotics Research, EarlyView.
Combining a biomimetic soft‐robot with deep‐learning data analytics sheds light on a unique peripheral dynamics seen in the biosonar system of bats: Bats modulate their ultrasonic biosonar signals upon emission as well as reception with variable, yet highly coordinated motion patterns of their noseleaves and pinnae.
