High‐Order Multipolar Excitations Governing Circular Dichroism in an All‐Dielectric Chiral Metasurface

Nanophotonics, Volume 15, Issue 11, 13 June 2026.
An all‐dielectric asymmetric gammadion metasurface exhibits visible circular dichroism governed by helicity‐selective multipolar excitations. Quadrupole‐dominated and weaker mixed‐mode resonances are identified, and their distinct near‐field optical chirality and angular responses are revealed, establishing a direct link between structural asymmetry ...

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

Brillouin Zone Folding‐Driven Topological Band Flips Based on BICs via Twisted Photonic Crystals

Nanophotonics, Volume 15, Issue 11, 13 June 2026.
Brillouin zone folding (BZF)‐driven topological band flips are demonstrated via twisted photonic crystals (PhCs) incorporating bound states in the continuum (BICs). Twist perturbation generates three new bands, each linked to either a BIC or a guided‐mode resonance (GMR).

Nanoscale Mapping of Plasmonic Charge Transport in Nano‐Resonators Based on Resistive Switching Materials

Advanced Functional Materials, Volume 36, Issue 46, 8 June 2026.
In this strategy, a conductive nano‐probe is employed to induce nanoscale phase transitions and map the nanoscale conductivity and trap density of GST films. By utilizing the contrasting properties of phase‐change states, nano‐resonators are fabricated that exhibit plasmonic conduction and dramatically different transport characteristics.
