Terahertz radiation is an electromagnetic radiation with the frequency band between infrared and microwave ranges. Devices with terahertz radiation may be used for example for security in public places improvement or in cancer diagnosis.
"Today, the issue of cancer at an early stage diagnosis is one of the most acute. The challenge is in the fact that cancer cells don’t differ from other cells of human body. But in the terahertz frequency range, they are immediately visible," said Alexander Atraschenko, the project manager and a member of the ITMO University Research Center for Nanophotonics and Metamaterials.
