Dramatic and Elusive Resonant Lattice Kerker Effect in the Nonlinear Response of Plasmonic Lattices

Nanophotonics, Volume 15, Issue 12, 25 June 2026.
Plasmonic metasurface that supports the resonant lattice Kerker effect, manifesting as the suppression of reflection in a narrow spectral range due to the simultaneous excitation of electric dipole and quadrupole modes, also gives rise to a substantial near‐field enhancement.

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.

Gaussian Wave Splatting for Computer-Generated Holography

ACM Transactions on Graphics
State-of-the-art neural rendering methods optimize Gaussian scene representations from a few photographs for novel-view synthesis. Building on these representations, we develop an efficient algorithm, dubbed Gaussian Wave Splatting, to turn these Gaussians into holograms.

Generating Circularly Polarized Light Using Hybrid Near‐Zero and High‐Index Materials

Advanced Photonics Research, Volume 7, Issue 6, June 2026.
A flat‐optics approach to manipulating the polarization state of light is proposed using evanescent‐wave interactions in hybrid epsilon‐near‐zero and high‐index materials. The design enables linear‐to‐circular polarization conversion in a wavelength‐scale device design without depending on patterning or bulky optics and operates in both reflection and ...

Multifunctional Metasurfaces for Bridging Terahertz Waves in Free Space and Waveguides

Advanced Physics Research, Volume 5, Issue 6, June 2026.
A multifunctional terahertz metasurface capable of simultaneous orthogonal polarization conversion and phase modulation is integrated onto a dielectric slab waveguide, thereby enabling efficient free‐space‐to‐guided‐wave coupling. By implementing tailored phase gradients on the metasurface, we demonstrate the formation of a focused spot within the ...
