In engineering, the terahertz gap is a frequency band in the THz region for which practical technologies for generating and detecting the radiation do not exist. It is defined as 0.1 to 10 THz ( wavelengths of 3 mm to 30 μm) although the upper boundary is somewhat arbitrary and is considered by some sources as 30 THz (a wavelength of 10 μm ...

Mar 22, 2022 · Between the beams of visible light and the blips of radio static, there lies a dead zone where our technology isn’t effective. It’s called the terahertz gap. For decades now, no one’s succeeded...

May 9, 2002 · Between the two technologies lies the so-called terahertz gap, where no semiconductor technology can efficiently convert electrical power into electromagnetic radiation. Köhler et al. 1 describe...

Jun 1, 2013 · New advances in different technologies have made the previously unused terahertz frequency band accessible for imaging systems. The ‘terahertz gap’ has a frequency ranges from ∼0.3 THz to ∼10 THz in the electromagnetic spectrum which in between microwave and infrared.

在实验室外，太赫兹辐射与宇宙微波背景辐射 (CMB)和其他天体物理现象有关，有助于寻找太空生命的起源。 1. 用微瓦和毫瓦功率将就. 幸运的是，当科学家们看到理解上存在空白时，他们马上投入研究。 自20世纪60年代以来，研究人员已经找到了利用傅里叶变换光谱仪获得高质量太赫兹光谱的方法。 在这个装置中，一个热源向固体、液体或气体样品发送微瓦的太赫兹功率，被样品反射或透射。 接下来，光束被分成两部分，每部分被镜子反射。 然后光束被重新组合，当一面镜 …

This is called Terahertz gap. In other words, Terahertz gap is the frequency range from 0.3 to 30 THz of EM spectrum as shown in the figure. The terahertz frequencies find applications in spectroscopy, pulsed imaging, impulse ranging, communication, sensing, security, mine detection, bio-chemical agent detection and so on.
