「Terahertz Technology」
The electromagnetic waves with the frequency range spanning from few hundreds of gigahertz (GHz) to few terahertz (THz) are known as terahertz waves. These waves can penetrate through wide variety of materials such as plastics, papers and cloths making them an alternative to X-rays in many applications such as security screening and non-destructive testing and evaluation. Moreover, wide variety of materials such as narcotics and explosives possess a spectral fingerprint in THz frequency region rendering them detectable, based on THz spectral imaging. Along with these applications, sub-terahertz waves are being exploited in wireless communication owing to their ability to satisfy the increasing demand for high speed data transfer. All these characteristics make the THz wave an attractive option in diverse fields from biomedical sciences and homeland security to information and communication technologies.
In this lecture, I will introduce the fundamental methods to emit and detect terahertz wave. Moreover, I will talk about various applications of these waves such as 2D and 3D imaging for non-destructive testing and analysis, spectroscopy for material identification and attenuated total reflection terahertz spectroscopy as a biomedical measurement tool.
