terahertzisäteilyteknologian
Terahertzsäteilyteknologia, often referred to as THz technology, is a field of science and engineering that focuses on the generation, manipulation, and detection of electromagnetic radiation in the terahertz frequency range. This part of the electromagnetic spectrum lies between microwaves and infrared light, typically spanning frequencies from 0.1 to 10 terahertz (THz), corresponding to wavelengths from 3 millimeters down to 30 micrometers. Terahertz waves possess unique properties that make them suitable for a variety of applications. They are non-ionizing, meaning they do not damage living tissues, which is crucial for biological and medical imaging. They can also penetrate many non-conducting materials like plastics, textiles, and ceramics, allowing for inspection and sensing through barriers.
The development of terahertz technology has been historically challenging due to the difficulty in efficiently generating
