Relation of Continuous Chirality Measure to Spin and Orbital Polarization, and Chiroptical Properties in Solids

open access: yesAdvanced Optical Materials, EarlyView.
This work quantifies chirality through the continuous chirality measure (CCM). The CCM is correlated to a variety of properties: spin‐orbit field, orbital angular momentum, circular dichroism, absorption dissymmetry factor (gCD) and the circular photogalvanic effect.

Miniaturized Single‐Photon Level Computational Complex Field Imaging System via Meta‐Optics

open access: yesAdvanced Optical Materials, EarlyView.
8192 Hadamard mask patterns generated by the digital micromirror device (DMD) are projected onto a micro target sample via a metalens. The corresponding modulated intensity spectrum encoded with the spatial information of the target is then captured by a photomultiplier tube (PMT) at the Fourier plane to recover both the amplitude and phase images ...

Cloaking and Antennas: From Theoretical Paradigms to Next‐Generation Intelligent Systems

open access: yesAdvanced Optical Materials, EarlyView.
The inception of electromagnetic cloaking sparked an immediate question: Can antennas be made invisible? Two decades later, this review charts the intertwined progress of major cloaking strategies (from transformation optics to scattering cancellation), metasurface technology, and their application to antennas, revealing how AI‐enabled devices are ...

Pseudo-colouring an ECG enables lay people to detect QT-interval prolongation regardless of heart rate.

open access: yesPLoS ONE, 2020
Drug-induced long QT syndrome (diLQTS), characterized by a prolongation of the QT-interval on the electrocardiogram (ECG), is a serious adverse drug reaction that can cause the life-threatening arrhythmia Torsade de Points (TdP).

Strong Resonant Enhancement in Polarization Anisotropy in Third Harmonic Generation from MoS2 Disks with Subtle Structural Ellipticity

open access: yesAdvanced Photonics Research, EarlyView.
Strong resonant amplification in polarization anisotropy in third harmonic generation (THG) response from isolated MoS2 disks with small structural ellipticity introduced during fabrication is reported. This is attributed to the high refractive index of the MoS2 disk that supports characteristic anapole resonances combined with the cubic dependence of ...
