Non‐Uniform Space‐Time‐Coding Modulation for Low‐Complexity Diagnostics of Reconfigurable Intelligent Surfaces

Advanced Electronic Materials, EarlyView.
A diagnostic method for reconfigurable intelligent surfaces (RIS) based on non‐uniform space‐time‐coding modulation is presented. Fault localization is achieved via amplitude‐only spectral measurements, eliminating the need for complex signal processing. A one‐to‐one mapping between harmonic components and RIS elements enables accurate detection.

Cooperative Atomic Mechanism of Emergent Tilted Magnetic Anisotropy

Advanced Electronic Materials, EarlyView.
This study reveals a novel atomic mechanism behind magnetic anisotropy, where single‐ion anisotropy at dilute atomic sites establishes a long‐range anisotropic magnetic order via exchange interaction. The resulting exchange‐induced anisotropy contributes comparably to the single‐ion anisotropy, offering a promising strategy for engineering magnetic ...
