Study of absorption-defined transmission windows in the terahertz band

Communications over the terahertz (THz) frequency band will feature a number of attractive properties, including miniature transceivers, terabit-per-second link capacities and high energy efficiency. Meanwhile, a number of specific research challenges have to be addressed to convert the theoretical estimations into commercially attractive and practical solutions. This paper presents the theoretical estimations of absorption properties of the THz frequency band from 0.3 THz to 3 THz which is chartered to explore by IEEE 802.15 THz Interest Group. The frequency band is called "no man's land" because the range is too high for RF (radio frequency) but it is also too low being considered of light.
