Asymmetric perfectly matched layer for the absorption of waves [PDF]
, 2002 The Perfectly Matched Layer (PML) has become a standard for comparison in the techniques that have been developed to close the system of Maxwell equations (more generally wave equations) when simulating an open system.

Computational Modeling of Geoelectrical Soundings using PML-FDTD
Journal of Microwaves, Optoelectronics and Electromagnetic ApplicationsThe Finite-Difference Time-Domain (FDTD) method was applied in order to analyze the transient responses of geoelectrical soundings that use circular electric dipole (CED) as source over stratified formations.

Plasmonic–Diamond Hybrids: Tunable Optical and Thermal Response for Nanoscale Applications
Advanced Theory and Simulations, Volume 9, Issue 6, June 2026.Finite‐element simulations demonstrate that nanodiamond cores precisely regulate plasmonic coupling, absorption, electric‐field confinement, and photothermal heating in gold and silver nanoparticle clusters. By identifying interparticle spacing, particle number, core conductivity, and surrounding refractive index as key design parameters, this work ...

Engineering Reports, Volume 8, Issue 6, June 2026.This study proposes an elastic wave reverse time migration (RTM) method to suppress multiple scattering noise in heterogeneous concrete. By effectively utilizing scattered wavefields, RTM enables high‐precision, robust imaging of sleeve grouting defects in prefabricated buildings, significantly outperforming traditional algorithms.

Dipole‐Quadrupole Model and Multipole Analysis of Resonant Membrane Metasurfaces
Laser &Photonics Reviews, Volume 20, Issue 12, 18 June 2026.Membrane metasurfaces, arrays of holes in a dielectric membrane, are appealing because they require no substrate and allow access to resonant near‐fields. However, developing a comprehensive theoretical description for them remains challenging. We introduce a semi‐analytical dipole‐quadrupole approach to analyze their resonant spectra at arbitrary ...
