在波长范围跨越高达10个数量级的电磁波段中,波长介于30μm～1mm的太赫兹(Terahertz,THz)辐射,这一曾被称为“THz空白”的电磁波段领域,引起科学家越来越多的兴趣。太,是兆兆的英译音,所以太赫兹辐射又称为T射线,属于远红外、亚毫米波范畴。早在上个世纪初,科学家就对该波段产 In the electromagnetic spectrum spanning wavelengths up to 10 orders of magnitude, Terahertz (THz) radiation with a wavelength in the range of 30 μm to 1 mm, a region of the electromagnetic spectrum known as “THz blank”, has caused more and more scientists interest of. Too, is the transliteration of trillion trillion, so the terahertz radiation, also known as T-ray, belongs to far infrared, submillimeter range. As early as the beginning of the last century, scientists produced this band
