Finite-difference time-domain simulation of partial discharges in a gas insulated switchgear

High Voltage, 2016
It is important to estimate the current magnitude and charge amount of a partial discharge (PD) in a gas-insulated switchgear (GIS). In this study, electromagnetic fields generated by a PD in an 84 kV-class three-phase GIS for testing have been measured ...

Epitaxial Integration of III–V Membrane Photodetectors With Lateral p–i–n Junctions on the Silicon‐On‐Insulator Waveguide Platform

Laser &Photonics Reviews, EarlyView.
Epitaxial growth forms III–V membranes directly atop the silicon waveguide layer on SOI, while in‐plane in situ doping defines lateral p–i–n InP/InGaAs junctions in a single growth step. The membrane photodetectors achieve 50 Gb/s NRZ‐OOK operation.

Virtual Overlay Staining With Plasmonic Oligomer Metasurface

Small, EarlyView.
A scalable plasmonic metasurface enables “virtual staining” of living cells by enhancing optical contrast from refractive index differences. Through electrostatically assembled nanoparticle oligomers on a mirror, cellular components such as nuclei, mitochondria, and lipid‐rich regions are visualized without molecular dyes. This approach simplifies cell
