Multispectrum Electromagnetic Response in FeNiHo/C Heterodimensional Structure for Microwave Absorption and Multimode Photodetection.

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.
