Rapid Diagnostics of Reconfigurable Intelligent Surfaces Using Space‐Time‐Coding Modulation
Advanced Functional Materials, EarlyView.A fast reconfigurable‐intelligent‐surface (RIS) diagnostics method is proposed based on spatio‐temporal modulation with orthogonal codes. Theoretical analysis demonstrates a clear distinction in code channel power between normal and faulty elements. Simulations validate its feasibility under high fault ratios and varying receiving angles.

Nitrogen‐Vacancy Magnetometry of Edge Magnetism in WS2 Flakes
Advanced Functional Materials, EarlyView.Using nitrogen‐vacancy magnetometry, the authors visualize room‐temperature stray magnetic fields localized at the edges of WS2 flakes. Their measurements reveal edge‐specific magnetization consistent with spin canting in antiferromagnetically coupled edge states.
