  • Composite structure for controlling absorptivity of radar and emissivity of infrared regions
    Patent number: 10439294
    Abstract: A technique of adjusting absorptivity of radar waves and emissivity of infrared waves by controlling the waves of the radar and infrared regions using a structure formed of a meta-material. A composite structure for controlling absorptivity and emissivity includes: a first anti-detection unit; and a second anti-detection unit stacked on the first anti-detection unit, wherein the first anti-detection unit is an absorber for absorbing electromagnetic waves of a first range input from an outside of the first anti-detection unit, and the second anti-detection unit is a selective emitter for selectively blocking emission of electromagnetic waves of a second range and selectively allowing emission of electromagnetic waves of a third range among electromagnetic waves that can be emitted to an outside of the second anti-detection unit.
