Design of electromagnetic sensor for metal wear particle detection in oil
The Journal of Engineering, Volume 2019, Issue 23, Page 8667-8670, December 2019., 2019 Wear is one of the common faults in the mechanical transmission system. Detection of wear particles in lubricating oil can detect and evaluate the wear degree of mechanical equipment. The electromagnetic sensor for metal wear particle detection can be connected in series with the oil circuit, which has the advantages of full liquid flow, simple ...

Space Weather, Volume 23, Issue 11, November 2025.Abstract Geomagnetic storms can induce geomagnetically induced currents (GIC) in power systems, posing threats to grid security. In this study, a GIC calculation model for the 500 kV power grid in Guangxi, China, is developed based on one‐dimensional (1D) and various three‐dimensional (3D) magnetotelluric (MT) impedance data.

Plasmonic near‐field scanning nanoscope with a cross‐polarization detection technique
Nanophotonics, Volume 8, Issue 10, Page 1731-1738, June 2018., 2018 Abstract A cross‐polarization detection technique was introduced to enhance the signal‐to‐noise ratio (SNR) of a plasmonic near‐field scanning nanoscope (PNSN) using the anisotropic reflection from a metallic ridge nano‐aperture. Assuming that the nano‐aperture is an resistor‐inductor‐capacitor‐equivalent circuit, we propose an analytic circuit model ...

A Finite Element Method for a Nonlinear Magnetostatic Problem in Terms of Scalar Potentials
Numerical Methods for Partial Differential Equations, Volume 41, Issue 2, March 2025.ABSTRACT The aim of this paper is to perform the analysis of a numerical method based on scalar potentials for solving a nonlinear magnetostatic problem in a three‐dimensional bounded domain containing prescribed currents and magnetic materials. The method discretizes a well‐known formulation of this problem based on two scalar potentials: the total ...

Principles and techniques of the quantum diamond microscope
Nanophotonics, Volume 8, Issue 11, Page 1945-1973, June 2018., 2018 Abstract We provide an overview of the experimental techniques, measurement modalities, and diverse applications of the quantum diamond microscope (QDM). The QDM employs a dense layer of fluorescent nitrogen‐vacancy (NV) color centers near the surface of a transparent diamond chip on which a sample of interest is placed.

High Voltage, Volume 9, Issue 4, Page 826-838, August 2024.Abstract Accurate calculation of short‐circuit electromagnetic force is crucial for both mechanical strength check and the optimal design of gas‐insulated transmission lines (GIL). Since the full 3D numerical simulation method is highly time‐consuming, a novel lightweight 2D multi‐slice electromagnetic field‐circuit coupled method for computing ...

Space Weather, Volume 22, Issue 4, April 2024.Abstract We introduce a new framework called Machine Learning (ML) based Auroral Ionospheric electrodynamics Model (ML‐AIM). ML‐AIM solves a current continuity equation by utilizing the ML model of Field Aligned Currents of Kunduri et al. (2020, https://doi.org/10.1029/2020JA027908), the FAC‐derived auroral conductance model of Robinson et al.
