Terahertz atmosphere
Web6 Aug 2024 · The advanced detectors on one of the observatory’s instruments, the German Receiver for Astronomy at Terahertz Frequencies (GREAT), enabled astronomers to distinguish the oxygen in the Martian atmosphere from oxygen in Earth’s atmosphere. Researchers presented their findings in a paper published in the journal Astronomy and … WebStrong absorption of terahertz radiation was realized which results in a complete blocking of the incident terahertz waves without pump (Figure 3(e)). When the G/NA device was illuminated by the optical pump, transmission window was open due to the photo-induced transparency of graphene, which leads to a distinctive modulation from absorption to …
