Electrospinning Machine | Multispectrum Electromagnetic Response in FeNiHo/C Heterodimensional Structure for Microwave Absorption and Multimode Photodetection

Challenge: Multispectral response technology is a key technique for developing multifunctional electromagnetic devices. Traditional methods rely on integrating complex multi-material systems, leading to larger device size and higher cost. 

Method: Professor Hao Xihong and Professor Li Yong from Inner Mongolia University of Science and Technology, Professor Li Lin from Harbin Normal University, and Professor Professor Cao Maosheng from Beijing Institute of Technology collaborated. Through polar interface engineering, a hierarchical heterodimensional structure composed of FeNiHo alloy and carbon matrix achieved autonomous multispectral coupling electromagnetic response between microwave and ultraviolet. 

Innovation 1: In the microwave band, the heterodimensional structure exhibits excellent microwave absorption performance, with a reflection loss as high as -46.87 dB and an ultra-wide absorption bandwidth of 8.96 GHz. 

Innovation 2: In the ultraviolet band, the multimode photodetector constructed from the heterodimensional structure shows good responsiveness and accurate decoding capability, which can be used for anti-interference ultraviolet communication. Notably, this metamaterial detector achieved analog signal communication for the first time through microwave-ultraviolet coupling response.
