There is a critical need for the development of dynamic IR materials that can be used to form device level components and systems necessary for mid to long wave infrared (3-12 m) applications. To meet these future needs, the team proposes to develop tunable optical elements based around metamaterial surfaces or metasurfaces. Metasurfaces are a class of engineered materials where arrays of sub-wavelength resonant elements are integrated within a surface to impress a desired spectral, directional, or polarization response. Metasurfaces also enable the development of extremely thin spectral tailoring (
Benefit: This Phase I effort will produce a metasurface design that will meet the needs of a high-dynamic range modulator that can be implemented into a wide range of systems needed to support the US Navys mission. The long-term goal for this program is the development of next generation MWIR/LWIR EM devices that possess critical functionality associated with the use of PCMs. The inclusion of PCMs for control of this portion of the EM spectrum is expected to enhance the current state of the art of C4ISR capabilities for future Naval applications. The development of dynamic infrared materials will be critical towards achieving devices, components and applications.
