Recent Development of Terahertz Science and Technology and It's Applications

Scientists found that half of the cosmic background radiation from the Big Bang is in the THz part of the spectrum, This fact seems unbelievable but it is the nature. It shows how much science involved in the THz frequency regime. The unique characteristics and great technological potential in physics , chemistry, biomedical engineering, astronomy, materials science and environment engineering of THz are presented in this paper，and the recent development of THz S&T is introduced. The rapid progresses and the urgent need result in the combination and mergence of the related basic research, development and the industrial applications of the THz S&T.
