SRA2 concentrates on providing the Soldier and Soldier platforms with the next level of capabilities for secure communications, multi-faceted situational cognition and visualization, and invulnerability to enemy detection and potentially for some cases, immunity to enemy EMP and spoofing technologies. The approach is an in depth examination of diverse segments of the EM spectrum currently under-exploited owing to inadequate scientific understanding of the basic physics of novel electronic, optical, and electromagnetic phenomena, or the unavailability of efficacious materials and devices to capitalize on recent progress in this understanding. For example, one project performs experimental and modeling studies to develop materials and devices that will bring hyperspectral resolution to thermal- and mid-IR imagers based on graphene and thereby produce a fully functional hyperspectral focal plane array. To tackle a longer wavelength domain a different project focuses on providing fundamental understanding of field-enhanced electroluminescence in quantum dots to enable up-conversion of LWIR and THz radiation to emissions in the visible. A third project features systematic studies of nanoplasmonic phenomena that enable non-intuitive shrinking of light waves with potential applications to compact radiation sources from THz to X-rays, secure communications, and more powerful obscurant particles. Another project seeks to synthesize novel mechano-optic, electro-optic and thermo-optic fibers that can be used to enable high bandwidth communications and reflectivity management of Soldier clothing and platforms. Finally, SRA2 includes in situ studies of electrode-electrolyte interfaces of an operating solid-state lithium ion battery to gain new fundamental understanding of the battery chemistry to improve the power density and shelf life of these power sources used in diverse equipment for Soldier communications, ISR, etc.
