Metamaterial with dual stealth functions in infrared and terahertz bands
In this study, an electromagnetic metamaterial with infrared (IR) passive stealth and terahertz (THz) active stealth functions is proposed. The device comprises an infrared stealth layer (IRSL) made of ZnS and SiO2, and a terahertz absorbing layer (TAL ...
