Terahertz Technologies and Future Security Environments

The terahertz (THz) frequency band is a fascinating and relatively unexplored part of the larger electromagnetic spectrum (EMS). THz can enable users to ‘see-through’ materials and structures and is now widely used in laboratory quality control testing, for non-destructive testing and transmitting information between servers in close proximity. However, because the transmitted signal degrades rapidly in the atmosphere, its application is limited to controlled settings. Soon, technological leaps will enable development of power sources that will prevent THz degradation in the atmosphere and at distance. When this happens, THz will be an exquisite tool to help the United States find and target items of interest. It will allow intelligence professionals and field operators to quickly discriminate targets based on composition, counter adversary concealment or deception techniques, and identify items of interest based on chemical resonance that is visible only through the use of THz imaging
