Abstract:
Methods and apparatus for providing a tunable absorption-emission band in a wavelength selective device are disclosed. A device for selectively absorbing incident electromagnetic radiation includes an electrically conductive surface layer including an arrangement of multiple surface elements. The surface layer is disposed at a nonzero height above a continuous electrically conductive layer. An electrically isolating intermediate layer defines a first surface that is in communication with the electrically conductive surface layer. The continuous electrically conductive backing layer is provided in communication with a second surface of the electrically isolating intermediate layer. When combined with an infrared source, the wavelength selective device emits infrared radiation in at least one narrow band determined by a resonance of the device. In some embodiments, the device includes a control feature that allows the resonance to be selectively modified. The device has broad applications including gas detection devices and infrared imaging.

Abstract:
The present invention provides a solar reflective-absorptive device, comprising: an IR reflective transparent conductive film; a flexible transparent conductive film; a layer of liquid crystal dispersion in polymer matrix or polymer dispersion in liquid crystal domains allocated between said flexible IR reflective transparent conductive film and said flexible transparent conductive film. The liquid crystal dispersion is in polymer matrix or polymer dispersion domains, and comprises metalorganic dye compositions with absorption in the visible and/or IR regions of solar spectrum. The aforesaid liquid crystal dispersion consists of nematic mixtures and/or cholestenc mixtures comprising of chiral mesogenic or none-mesogenic chiral materials in nematic for IR absorption and/or broadband cholesteric materials for dynamic (electrically tunable) IR and visible absorption. The switching capability of the device will be carried out through reorientation of the liquid crystal dispersion sandwiched between said at least one transparent IR-reflective flexible conductive support and said transparent flexible conductive support.
