Metamaterials: Hierarchical Metamaterials for Multispectral Camouflage of Infrared and Microwaves (Adv. Funct. Mater. 10/2019)

In article number 1807319, Hyung Hee Cho and co-workers successfully demonstrate a hierarchical metamaterial (HMM) for multi-spectral control. The intermediate dielectric layer enables the integration of the microwave absorber and infrared selective emitter. The HMM shows not only the signature control against the microwave and infrared spectra, but also the dissipation of the reduced emitting energy through the undetected band of infrared waves.
