	1	Covert infrared image encoding through imprinted plasmonic cavities显示文摘Functional surfaces that can control light across the electromagnetic spectrum are highly desirable.Plasmonic nanostructures can assume this role by exhibiting dimension-tunable resonances that span multiple electromagnetic regimes.However,changing these structural parameters often impacts the higher-order resonances and spectral features in lower-wavelength domains.In this study,we discuss a cavity-coupled plasmonic system with resonances that are tunable across the 3–5 or 8–14μm infrared bands while retaining near-invariant spectral properties in the visible domain.This result is accomplished by regime-dependent resonance mechanisms and their dependence on independent structural parameters.Through the identification and constraint of key parameters,we demonstrate multispectral data encoding,where images,viewable in the infrared spectral domain,appear as uniform areas of color in the visible domain—effectively hiding the information.Fabricated by large area nanoimprint lithography and compatible with flexible surfaces,the proposed system can produce multifunctional coatings for thermal management,camouflage,and anti-counterfeiting.
