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.

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 ...

A novel large aperture metalens design strategy achieves broadband achromatic imaging across the visible spectrum (400–680 nm) with a 100° field of view. By incorporating forward mapping optimization and a hybrid algorithm framework, this approach overcomes the limit between aperture size, field of view, and chromatic aberration correction, providing a

Lithography‐free spaced TiO2 NT arrays unlock tunable broadband absorption from THz to UV. By harnessing annealing‐driven phase transitions, strong phonon–polariton resonances emerge in the 1.4–3.6 THz range, whereas high absorptance persists beyond 10 THz.

Multiple Bound States in the Continuum in Deep‐Subwavelength Nonlocal Polar Dielectric Nanoparticles
Spatial dispersion in polar‐dielectric core–shell nanoparticles enable multiple deep‐subwavelength bound states in the continuum through longitudinal‐transverse hybrid modes. By suppressing radiative damping at finite geometrical parameters, these nonlocality‐induced BICs provide a compact platform for high Q light confinement, enhanced light–matter ...
