摘要： A thermal decoy system contains electro-resistive fabric which warms the air within a polymer envelope transmissive to infrared radiation. The thermal decoy system thereby produces a thermal signature comparable to that of a human, which will preemptively trigger passive-infrared sensors, thereby neutralizing such sensors' capability to detect nearby persons.

摘要： Systems according to the present disclosure provide one or more surfaces that function as power transferring surfaces for which at least a portion of the surface includes or is composed of “fractal cells” placed sufficiently closed close together to one another so that a surface (plasmonic) wave causes near replication of current present in one fractal cell in an adjacent fractal cell. A fractal of such a fractal cell can be of any suitable fractal shape and may have two or more iterations. The fractal cells may lie on a flat or curved sheet or layer and be composed in layers for wide bandwidth or multibandwidth transmission.

摘要： Subwavelength conducting particles can be arranged on conducting surfaces to provide arbitrary thermal emissivity spectra. For example, a thermal emissivity spectrum can be tailored to suppress a thermal signature of an object without sacrificing radiative cooling efficiency.

摘要： A site-specific photographic camouflage arrangement and method for making the same are provided. The site-specific photographic camouflage arrangement includes a digital photographic image and distorting disruptive patterns placed on the digital photographic image to create visual confusion to disguise the recognizable form of a camouflaged object by breaking up its outline.

摘要： A camouflage pattern is provided that appears to have infinite focus and depth of field even at 100 percent size for the elements in the camouflage pattern. Generally, three-dimensional (3D) models of elements to be used in the camouflage pattern are captured or generated. The models are then arranged in a scene with a background (e.g., an infinite background) via 3D graphics editing programs such as is used to render computer generated graphics in video games and movies. A two-dimensional (2D) capture of the scene thus shows all visible surfaces of the elements in the scene in focus at all depths of field. The elements may or may not be shaded by one another from the perspective of the image capture location in the 3D environment.

摘要： A light field (LF) display system for augmentation of a vehicle. The LF display system includes LF display modules that form a surface (e.g., interior and/or exterior) of a vehicle. The LF display modules each have a display area and are tiled together to form a seamless display surface that has an effective display area that is larger than the display area. The LF display modules present holographic content from the effective display area.

摘要： A cloaking apparatus and method are disclosed herein. The cloaking apparatus for cloaking a target object using meta-material includes a compensation unit, and a cloaking cell. The compensation unit is disposed in a second space surrounding part of a first space including the target object, and is composed of a first meta-material having a predetermined negative refractive index. The cloaking shell is configured to surround part of the compensation unit, and is composed of a second meta-material. The negative refractive index may be a negative refractive index that is adapted to cloak the target object by compensating for the positive refractive index of the first space.

摘要： The present invention relates to invisibility device in, particular to electromagnetic cloaking devices and their method of making the same. The present invention is related to designing the cloak device with a base made of first material and strips of second material placed on the said base. The present invention proposed a design strategy through which cloaking at multi band can be achieved even with single layer of cloaking device.
