报告内容简介: 

     Terahertz wave is situated between the infrared and microwave spectrum in the electromagnetic spectrum with a frequency range from 0.1 to 10THz. As different molecules absorb unique amounts of energies for their intermolecular activities in the Terahertz range, Terahertz wave can be used to detect rotational and vibrational activities of a specific molecule. Thus, different materials can be characterized by their unique vibrational, structural and electronic properties, giving rise to exclusive fingerprint spectra. Terahertz spectroscopy is also safe to be used as it can penetrate many materials, yet it is non-ionizing. In addition, Terahertz spectroscopy is highly accurate due to its fast sampling time of sub- picosecond in showing peak spectral response. Also, with the use of Terahertz Spectroscopy, material dependent parameters such as complex refractive index can be calculated without the use of the complicated Kramer’s- Kronig relations.
     Recent developments in the field of Terahertz has resulted in the discovery of its potential application in numerous fields.  In Institute of Materials Research & Engineering, researchers have been working on the THz hardware prototype development, as well as various applications, such as biomedical and food. In this presentation, I will present the updated research results related to THz application in various applications.
