Space‐Time‐Coding Metasurfaces Enabling Programmable Range‐Angle‐Dependent Energy Auto‐Scanning

Nanophotonics, Volume 15, Issue 14, 27 July 2026.
This paper presents a novel energy auto‐scanning system based on a space‐time‐coding metasurface. By applying progressive time‐delayed, time‐varying phase modulation, the system generates non‐uniform, temporally evolving electromagnetic field distributions across both angle and range.

Fully Polarimetric Radar Cross‐Section and High‐Resolution Range Profile Co‐Modulation via Diversely Time‐Modulated Metasurface

Nanophotonics, Volume 15, Issue 14, 27 July 2026.
A diversely time‐modulated metasurface enables broadband co‐modulation of fully polarimetric radar cross section and high‐resolution range profiles. By integrating anti‐parallel PIN diodes and programmable temporal coding, the platform dynamically redistributes scattering among HH/VV and HV/VH channels, generating tunable target weakening, false ...

Increasing of Q Factor of Quasi‐Bound States in the Continuum With Increased Asymmetry Parameter in a Silicon Metasurface Array

Nanophotonics, Volume 15, Issue 14, 27 July 2026.
Quasi‐bound states in the continuum (qBICs) can support resonances with high quality (Q) factor. Traditionally, maintaining a high Q factor requires a small α, which brings significant challenges for nanofabrication. In contrast, our study finds an increase in the Q factor with increasing of α in a metasurface array composed of Si blocks with circular ...
