  • 3-DIMENSIONAL RESONANT STRUCTURE BASED INFRARED SELECTIVE EMITTER CAPABLE OF BROADBAND AND INCREASED EMISSION
    Publication number: 20230314677
    Abstract: Proposed is a 3-dimensional resonant structure-based infrared selective emitter capable of maximizing the infrared selective radiation function by broadening the emissivity in the non-detection bands with resonance phenomena between multiple resonator units at the same time as securing infrared camouflage and energy dissipation-resultant surface thermal stability by reducing the emissivity significantly in the infrared detection band and selectively dissipating energy to the non-detection bands.

  • INFRARED SELECTIVE EMITTER WITH IMPROVED WEAR RESISTANCE
    Publication number: 20230266508
    Abstract: The present invention provides an infrared selective emitter that can selectively emit infrared energy in a desired wavelength band, can be easily applied to a curved surface due to its flexible properties, and can protect the formed surface structure of the infrared selective emitter from external stimuli such as friction, thereby improving wear resistance and maximizing the function of infrared selective emission.

  • FLEXIBLE INFRARED SELECTIVE EMITTER AND MANUFACTURING METHOD THEREOF
    Publication number: 20230221618
    Abstract: The present invention provides an infrared selective emitter in which since infrared energy can be emitted in a desired wavelength band by adjusting a metamaterial having a repeating structure on a plane, infrared camouflage is possible by attaching to the surface of the shape of an object to be camouflaged, and at the same time, the infrared selective emitter has flexible characteristics that can be applied to curved surfaces without limitations on the shape of an object.

  • AIRFOIL WING-SHAPED AIRCRAFT
    Publication number: 20220106035
    Abstract: Proposed is an airfoil wing-shaped aircraft including a body having a wing-shaped longitudinal cross-section and having an upper surface on which a shape of a concave curvature-surface portion is formed along a center axis in a streamwise direction, a fluid inlet being formed in each of the opposite lateral sides of a leading portion of the body, and a fluid output being formed in each of the opposite lateral sides of a tail portion of the body, wherein a duct connects the fluid inlet and the fluid outlet to each other.
