Nanophotonics, Volume 15, Issue 15, 13 August 2026.This work presents a NURBS‐enabled metasurface design framework that combines freeform meta‐atom parameterization with Transformer‐based deep learning. The unified mathematical representation expands geometric degrees of freedom while enabling efficient optical‐response prediction and inverse design.

Nanophotonics, Volume 15, Issue 15, 13 August 2026.Conceptual illustration of the retro‐reflective and transmissive metasurface (RRTM). The blue radar establishes communication with the UAV via the transmissive mode, whereas the purple surveillance radar acquires the status of friendly units through the retro‐reflective mode and the two modes operate simultaneously within the same decoupled aperture ...

Broadband Electromagnetic Field Prediction at Unseen Wavelengths via Physics‐Guided Neural Operators
Nanophotonics, Volume 15, Issue 15, 13 August 2026.A physics‐guided neural operator is trained on electromagnetic field distributions at discrete wavelengths across diverse nanophotonic structures. At inference, given any permittivity map and query wavelength, the model predicts continuous broadband electric‐field distributions with full‐wave accuracy, including wavelengths unseen during training ...

Nanophotonics, Volume 15, Issue 15, 13 August 2026.The vortical differential scattering of spatiotemporal optical vortices by chiral particles is investigated. It is revealed that a longitudinal orbital angular momentum component is essential for inducing vortical dichroism, whereas a purely transverse OAM yields no chiral response.

Metasurface‐Enabled Active‐Like Passive Radar
Advanced Science, Volume 13, Issue 44, 7 August 2026.A programmable space‐time‐coding metasurface embeds distinct spatiotemporal tags into ambient wireless signals, allowing passive radar to operate in an active‐like manner. By enabling code‐correlated reconstruction under interference, the approach supports robust real‐time UAV tracking in complex environments and points to intelligent, low‐power ...
