Simulating the Generation and Guided Propagation of Terahertz Radiation using COMSOL MultiphysicsJason A. Deibel
Electromagnetic waves within the Teraherz frequency spectrum are common in medical techonolgy applications, such as imaging, spectroscopy and drug detection.
In this presentation, we explain how Teraherz Radiation is used in different applications, how to produce Electromagnetic waves in the Teraherz frequency, and how to analyze them.
Simulations in COMSOL Multiphysics are included as special case studies: A Photoconductive antenna, analysis of a waveguide coupling, and FEM Modeling of photonic crystals. Our results are validated either with the analytical solution, if there is one, or with experimental results.
Keynote speaker's biography: Jason Deibel is a Postdoctoral Research Associate in the Department of Electrical and Computer Engineering at Rice University in Houston, Texas where he is a member of Professor Daniel Mittleman's research group. As part of his work at Rice, Jason is a participant in the Intelligence Community Postdoctoral Fellowship Program. In the early fall of 2006, he will be a Royal Society visiting researcher at the University of Leeds, UK.
Jason's research interests include terahertz emission spectroscopy of novel inorganic and organic semiconductors, metamaterials, and finite element method simulations of terahertz radiation phenomena such as photoconductive antennas and waveguides. His dissertation focused on the use of nonlinear optical polymers in ultrafast electro-optic sampling measurements. Jason received a BA in physics and mathematics from Transylvania University in 1997. He earned his PhD in Applied Physics from the University of Michigan, Ann Arbor in 2004.
J. A. Deibel was one of the keynote speakers at the COMSOL User's Conference, fall 2006 in Boston.
