S2 Corporation

S2 Corporation is a Bozeman, Montana photonics company that reads the radio spectrum the way a hologram stores an image - all at once. Its core technology, spatial-spectral (S2) holography, uses a cooled, sugar-cube-sized crystal doped with rare-earth atoms as an optical computer that captures and processes radio frequencies across enormous instantaneous bandwidths (0.03 to 110 GHz). Packaged as the Extreme Bandwidth Analyzer and Correlator (EBAC), the technology serves electronic warfare, signals intelligence, RF spectrum monitoring, emitter geolocation, and data mining for U.S. defense and intelligence customers including DARPA and IARPA.
