Efficient solution on solving 3D Maxwell equations using stable semi-implicit splitting method

AIP Advances, 2016
In this paper, we propose an efficient solution on solving 3-dimensional (3D) time-domain Maxwell equations using the semi-implicit Crank-Nicholson (CN) method for time domain discretization with advantage of unconditional time stability. By applying the

Exposure to 5G Radiofrequency and Physiological Effects in Healthy Young Adults: Insights Into Heart Rate Variability and Salivary Stress Biomarkers

Bioelectromagnetics, Volume 47, Issue 5, July 2026.
ABSTRACT This study investigated the potential impact of fifth‐generation (5 G) radiofrequency (RF) on the autonomic nervous system (ANS). Electrocardiograms (n = 43) and salivary samples (n = 33) were collected from healthy young volunteers before, during, and after exposure to a 3.5 GHz frequency (electrical field intensity ~1–2 V/m) emitted by an ...

Novel Research on a Finite-Difference Time-Domain Acceleration Algorithm Based on Distributed Cluster Graphic Process Units

Applied Sciences
In computational electromagnetics, the finite-difference time-domain (FDTD) method is recognized for its volumetric discretization approach. However, it can be computationally demanding when addressing large-scale electromagnetic problems.

Modeling of Elves Doublets Based on Variations of the Lightning Return Stroke Current

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Elves are transient luminous events appearing above thunderclouds. They are produced by high peak current lightning events. They occasionally appear as doublets or in general as multiplets. We model elves doublets by setting the temporal and spatial variations of the return stroke current amplitude and we show that our modeling results are ...

Dynamic Holographic Display With Multiplexed Dielectric Metasurfaces

Nanophotonics, Volume 15, Issue 12, 25 June 2026.
Based on multiplexed metasurfaces, we show hybrid multiplexing of polarization, wavelength, and orbital angular momentum can be applied for dynamic tuning. Our strategy presents a highly compact and efficient solution for high‐capacity, multi‐dimensional holography, with promising applications in advanced displays, data storage, optical encryption, and

Toward Reliable Spectroscopic Analysis of Reaction Kinetics in Polaritonic Chemistry

Nanophotonics, Volume 15, Issue 11, 13 June 2026.
Vibrational strong coupling has been reported to modify chemical reaction rates, yet its mechanism remains unresolved. We expose pitfalls in UV/Vis‐based kinetic analyses and emphasize the need for standardized cavity protocols. ABSTRACT Recent reports suggest that chemical reaction rates can change inside an optical cavity.

Chiral Light–Matter Interaction for Controlling Nanoplasmonic Fields

Nanophotonics, Volume 15, Issue 11, 13 June 2026.
This paper demonstrates plasmonic circular dichroism using gold nanoparticle dimers that exhibit high near‐field contrast under left‐ and right‐circularly polarized illumination. SNOM mapping reveals that the dichroic behavior of the dimers transforms hot spots into cold spots with full optical control. Additionally, the eigenmode excitations and their
