Abstract
In this paper, a 3D meta-atom-based structure is constructed for the multifunctional compatible design of visible, infrared, and microwave. To achieve high performance, a novel dispersion tailoring strategy is proposed. Through the incorporation of multiple controllable losses within the 3D meta-atom, the dispersion characteristics are tailored to the desired target region. The effectiveness of the strategy is verified with an error rate of less than 5%. A proof-of-concept prototype is designed and fabricated, exhibiting high visible transparency, low infrared emission of 0.28, and microwave ultra-broadband absorption with a fractional bandwidth of 150% under 2.7 to 18.7 GHz. This work contributes a novel design strategy for the development of high-performance multispectral stealth materials with wide applications.
