Jeffrey Jau came to University of Missouri--Rolla in fall of 2003. The intended major field of studying was physics, and remained to be physics throughout the college career. A senior who will complete the requirements for B.S. in physics by May of 2006, and hoping to be able to pursue a career in photonic devices.
Abstract
Mesoscopic metal wire and disordered optical waveguide are two examples of quasi-1D random scattering media. The goal of this project is to develop a flexible numerical code for examining wave transport through the random media. Evolution of electric field from the beginning to the end of the system is described with a set of transfer matrices in terms of open and closed channels of the waveguide. To achieve numerical stability we also implement self-embedding procedure. The simulation will run under various regimes of wave transport: from diffusion to Anderson localization. Consistent account of closed channels in our approach will allow to determine the importance of evanescent fields on the statistics of mesoscopic transport.
