Mesh material is presented for a hunting blind with a camouflage pattern printed on a first side and a second side with a color coating. The mesh material is partially transmissive such that a portion of incident radiation from an exterior of the hunting blind is reflected back into the exterior, a portion of incident radiation from an interior of the hunting blind is transmitted through the mesh material to the exterior and an intensity ratio of the reflected portion to the transmitted portion during daylight conditions is above a threshold value such that the exterior of the hunting blind is visible from the interior and the interior of the hunting blind is not visible from an exterior of the hunting blind. A hunting blind is also provided that includes a frame including frame members and panels of the mesh material attached to the frame members.

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.

A system, apparatus, composition and methods for producing a modular, ultra-thin, ultra-lightweight thermal camouflage, thermal signature mitigation and thermal insulation system. The thermal management system may comprise one or more composite layers or combinations of ultra-thin and ultra-lightweight non-woven stealth coated substrates. Each composite layer may be coated with specific components to create different thermal camouflage through a biomimicry application process of absorbance, reflective, protective layering, thermal signature mitigation, and/or thermal insulation system capabilities. Layers can be combined to enable dynamic stealth camouflage tunable performances of reflectivity, transmission, emissivity, or absorption in selective visible, near infrared, and infrared wavelength bands whereby each substrate has a unique EM wave propagation control or thermal signature mitigation characteristics. Embodiments enable thermal camouflage, thermal signature mitigation, and thermal insulation solutions that are adaptable to specific battlefield scenarios or environmental requirements.

A base for supporting a hunting blind includes a plurality of outer frame members connected to one another to form an outer frame, at least one floor panel positioned on a top surface of the outer frame, and at least one of the floor panels defining at least one aperture to receive a storage bin. A plurality of support members may be configured to support the outer frame, the support members being configured for insertion into a ground surface. A height of each support member relative to the ground surface may be adjustable to provide a level position for the outer frame.
