Boosting the Magnetic Response of a Composite Nanostructure in the Near‐Visible Region with a Fano Resonance

open access: yesAdvanced Photonics Research, Volume 7, Issue 1, January 2026.
Optical simulations of composite plasmonic split‐ring resonators show that a magnetic response can be obtained at wavelengths near the visible regime. The response is further increased by extending the geometry and enabling a Fano resonance through the coupling of magnetic dipoles.

Strong and Weak Coupling Nanophysics with Free Electron Beams

open access: yesAdvanced Optical Materials, Volume 13, Issue 34, December 2, 2025.
This paper focuses on a short review of the study of the coupling between optical excitations at the nanometer scale, made possible by recent advances in free electron beam spectroscopies. In particular, plasmon–plasmon, plasmon–exciton, and plasmon–phonon couplings are reviewed. Abstract The work of Luis M.
