摘      要：Camouflage technology has attracted growing interest for many thermal *** experimental demonstrations of thermal camouflage technology have not adequately explored the ability to continuously camouflage objects either at varying background temperatures or for wide observation *** this study,a thermal camouflage device incorporating the phase-changing material Ge2Sb2Te5(GST)is experimentally *** has been shown that near-perfect thermal camouflage can be continuously achieved for background temperatures ranging from 30℃ to 50℃ by tuning the emissivity of the device,which is attained by controlling the GST phase *** thermal camouflage is robust when the observation angle is changed from 0°to 60°.This demonstration paves the way toward dynamic thermal emission control both within the scientific field and for practical applications in thermal information.
