Webb9 9 Absorption of UV radiation in the gaseous atmosphere is primarily due molecular oxygen O2 and ozone O3. Figure 6.5 Spectral absorption cross-sections of O2 and O3 NOTE: a) Bands of O2 and O3 at wavelengths < 1 µm are electronic transitions. b) These absorption bands are relatively uncomplicated continua because practically all Webb1 feb. 2024 · Many researchers have been motivated by these results to establish a broad variety of absorbers for the THz (Tao et al. 2008 ), near-infrared (Liu et al. 2010 ), mid-infrared (Aydin et al. 2011 ), and visible spectrum range. This study has been useful in the field of maximum absorption and development for the terahertz range (THz) gadgets.
