| Zusammenfassung: | © 2025 Wiley‐VCH GmbH. Multispectrum response technology is the key to developing multifunctional electromagnetic devices in cross-field applications. Traditional methods rely on integrating complex multi-material systems, leading to bulkier and costlier devices. Here, a hierarchical heterodimensional structure composed of FeNiHo alloy and carbon matrix achieves autonomous multispectrum-coupling electromagnetic response between microwave and ultraviolet through polar interface engineering. In the microwave band, the heterodimensional structure exhibits outstanding microwave absorption performance with high reflection loss of -46.87 dB and ultra-wide absorption bandwidth of 8.96 GHz. Furthermore, the antenna arrays based on the heterodimensional structure demonstrate in situ microwave frequency-agile property by a coupled ultraviolet stimulation, where the largest frequency modulation range reaches 5.05 GHz in Ku-band. In the ultraviolet band, multimode photodetectors constructed by the heterodimensional structure possess excellent responsivity and accurate decoding ability for anti-interference ultraviolet communication. Particularly, the metamaterial detector achieves analog signal communication for the first time by microwave-ultraviolet coupling response. This work pioneers a novel approach to developing multifunctional electromagnetic materials for multispectrum applications |
