My research involves using terahertz
time
domain spectroscopy to study the properties of certain
materials.
Terahertz
radiation
lies between the microwave and far infra red part of the spectrum. It
is the least unexplored part of the electromagnetic spectrum.
However, recent studies in this frequency range have unraveled useful
information about the vibration modes of certain molecules.
Also, terahertz (unlike x-ray radition) is non-ionizing and thus could
be
used to image tissue with no damage to body cells. This
imaging
could be employed to 3D imaging of teeth, and effective detection of
skin cancers like basal cell carcinoma. Last, it could be used for
airport
screening of materials that would never be spotted by the
present screening techniques.
My projects thus far have related to thz waveguiding. My
current project involves a numerical and experimental study of the
propagation of thz radiation between two metal wires. I used a software
called COMSOL multiphysics for my simulations. The following
presentation
contains pretty pictures from my simulation.
And
here
is my submission to the 2007 Confrence on Lasers and Electro-Optics
