"Terahertz Spectroscopy: The Generation and Detection of a Terahertz Pulse"
Lara Northrop, Advisor: Dr. M. Elizabeth Parks
The relatively new technique of time domain terahertz spectroscopy has gained much respect in
the field of condensed matter physics as one of the best ways to learn about the response of a
material in this frequency range. In the experimental apparatus, the terahertz pulse is created by a
generator antenna and guided by a mirror system to the sample. When the pulse is transmitted
through the sample, prperties of the terahertz pulse become altered. The alteration of the pulse
by the sample is determined by measuring the electric field of the pulse at a detector antenna.
This experimental methos allows the complete characterization of a sample from a single
measurement of transmission.
