Terahertz Absorption Spectroscopy

Research Projects:

Waveguide – based Terahertz Absorption Spectroscopy

Absorption spectroscopy, which uses the absorption resonances in materials coming from vibrational and rotational modes for detection and concertation sensing of different samples in a solution, is a mature technology in mid – infrared range. This spectroscopy method is extends to the THz range of frequency due to simple absorption line shapes for large molecules in this range. We are trying to develop an efficient dielectric waveguide – based platform for absorption spectroscopy in the frequency range up to 1THz.

Main aspects of  the project:

• THz absorption spectroscopy.
• Dielectric waveguide platform.
• THz dielectric slot waveguide.
