An Optically Transparent Infrared Selective Emitter accompanied by Customizable Digital Distribution

In this paper, a new type of IR selective emitter(ISE) based on five layers of ITO/ZnS is presented. This paper proposes an ISE with excellent selective emission performance in 5 ~ 8 μm undetectable band and high transmittance in visible spectrum. Moreover, the selected emittance material is put on the microwave absorber as a patch. Based on the size of the patch, the four units are arranged as digital pixels, which makes the target emissivity and background emittance more integrated, which is helpful for microwave absorption. This work not only improves the ability of IR emission and heat dissipation, but also improves the application of IR, visible and microwave compatibility.
