a Illustration of the thermal camouflage with different background temperatures. The surface of the tank’s upper body is covered with a GST-Au double-layered film. Perfect camouflage can be achieved by changing the GST phase. b An image of the experimental setup. There are two heating stages in our setup. One is used to anneal the background (blackbody), with the temperature changing from 30 °C to 50 °C, and the other is used to anneal the object (emissivity-tunable sample) at a fixed temperature 60 °C. c The measured emissivities are collected at normal angle for aGST-Au and cGST-Au devices
