Abstract
A multiple and broadband stealth structure comprises a radar absorption unit that absorbs broadband microwave, a low-frequency transmission filter unit that is stacked on an upper portion of the radar absorption unit, and an infrared radiation unit that is combined with the low-frequency transmission filter unit to selectively emit infrared ray, thereby selectively controlling the infrared emissivity of the surface to emit infrared radiation only through an atmospheric absorption window with a low infrared transmittance and to avoid the infrared detection system.
