About the Event

I will present theoretical and numerical results on imaging in random waveguides. Most of the talk will be for sound waves in waveguides with bounded cross-section, with randomly perturbed boundary and/or wave speed. If time permits, I will also discuss extensions to electromagnetic waves. I will show how to quantify long range net scattering in random waveguides and will contrast the loss of coherence caused by interior inhomogeneities vs. random boundaries. The results show that we should use different imaging methods to mitigate scattering in the random medium and/or that from the random boundary. I will present numerical results that illustrate the analysis.
