Detailed Analysis of Water Vapor with All Isotopologues, Air Gas Mixtures and Air Molecules at Terahertz Range

The scarcity of radio spectrum led regulators to consider new frequency bands including Terahertz frequencies between 0.275 and 1 THz, which is previously reserved only for passive services such as satellite telemetry and radio astronomy. One of the major advantages of Terahertz bands is the available bandwidth. For example, future generation cellular networks would be able support extreme throughputs via Terahertz backhaul links. But the medium that the electromagnetic waves propagate need to be analyzed by this way theoretical results will turn to practical and commercially attractive results. This work will give the channel characteristics of detailed analyzes of CO₂, H₂O, O₂, USA model (high latitude, winter)—USA model (tropics) between 0.275 and 10 THz range. The developed model in this paper evaluates the total absorption loss, path loss, SNR and capacity properties. The water vapor–H₂O (which is the biggest enemy of high frequencies) with all isotopes is analyzed in this paper. This paper also presents the theoretical estimations of absorption properties of CO₂, H₂O, O₂, USA model (high latitude, winter)—USA model (tropics) at the THz frequency band from 0.275 to 10 THz.
