What is Terahertz?

Terahertz is a radiation wave in the electromagnetic spectrum and it travels in a line of sight and is non-ionizing. Like microwaves, terahertz radiation can penetrate a wide variety of non-conducting materials; clothing, paper, cardboard, wood, masonry, plastic and ceramics. The penetration depth is typically less than that of microwave radiation. As it is non-ionizing, it have a different aspect from the ionizing X-ray.

Terahertz is also a frequency unit, 1THz=1000GH, people’s research on terahertz is mainly between 0.1THz~10THz.

THz-Spectrum
In the 1980s, American scientists discovered an infrared light that matches the vibration frequency of human cells — Terahertz wave. And it can resonate with human cells to activate the body cells, called by scientists — “Wave of Life”.
  • In 2004, the US government rated terahertz technology as one of the ”ten Technologies that will change the world of the future.
  • In 2005, Japan listed terahertz technology as the first of the "Ten Key Strategic Objectives of the National Pillars", and the nation is engaged in research and development.
  • In 2005, China listed THz technology as one of the ‘Ten Key Strategic Goals of National’
  • In 2014, China held the ”Xiangshan Science and technology conference” to formulate a plan for accelerating research on the application of terahertz technology in biomedicine.
Terahertz waves are becoming ever more important in science and technology. This technology have being in research in medical imaging, security, communication, manufacturing and other scientific use and imaging.
