This article introduces and validates a stealth metasurface that is compatible with visible, infrared, and microwave frequencies, designed to combine structural color for visible camouflage, low infrared emission, and extensive microwave absorption. The complete structure is constructed using two distinct layers: a visible-infrared layer (VIL) for coloration and infrared management, and a microwave absorption layer (MAL) for microwave absorption.. In the design of VIL, frequency selective surfaces (FSS) with SiO 2 /Ag/ZnO/Ag multilayer film structures were designed to achieve selective reflection of visible light for multiple structural colors, low infrared radiation for infrared stealth, and high microwave transmittance simultaneously. For MAL, a synergistic approach of equivalent circuit method (ECM) and particle swarm optimization algorithm (PSO) is adopted to design and optimize square metasurfaces for 8-18GHz microwave absorption. Then the visible-infrared-microwave compatible stealth metasurface can be made by combining VIL and MAL. In conclusion, the metasurface structure presented in this article fulfills the requirements for multiband stealth in contemporary warfare and holds significant potential for widespread application.
