Nanophotonics, Volume 15, Issue 10, 27 May 2026.We demonstrate an indirect magneto‐optical coupling mechanism that overrides the symmetry‐induced suppression of s‐polarized TMOKE. A quasi‐two‐dimensional grating coordinates orthogonal resonances to establish a near‐zero reflection background and maximal near‐field asymmetry, achieving a theoretical‐limit TMOKE of ∼2.

Physical properties of the tunic in the pinkish-brown salp Pegea confoederata (Tunicata: Thaliacea)
Zoological Letters, 2018 Background Invisibility in the water column is a crucial strategy for gelatinous zooplanktons in avoiding detection by visual predators, especially for animals distributed in the euphotic zone during the daytime; i.e., surface dwellers that do not ...

Nanophotonics, Volume 15, Issue 9, 13 May 2026.Mechanically reconfigurable metasurfaces enable high‐capacity optical storage and holography due to low cost/complexity. A differentiable inverse design framework maps meta‐atom geometries to multichannel optical responses via deep neural networks. Rotatable cascaded metasurfaces optimized through this pipeline achieve pixel‐level holography with 288 ...
