Speaker: Assoc. Prof. Özgür Özdemir, Istanbul Technical University

Topic: "Microwave Imaging in Layered Media"

Location: Middle East Technical University, Ankara, Turkey

Abstract: Microwave imaging of buried targets in inhomogeneous/layered media have been a very important research area due to its wide range of applications: biomedical applications, through wall surveillance, nondestructive testing in material science, etc. Most of the developed imaging methods require the knowledge of the background Green’s function which may be very costly. This is particularly the case for non-smooth-interfaced and/or stratified media where the Green’s function can only be calculated numerically. This would dramatically increase the computational cost of the methods and therefore constitutes one of their main drawback for this background configuration.

In this talk, we will present our recent work on efficient microwave imaging techniques  for layered medium problems.  We have developed a new formulation of the scattering problem,i.e, Cauchy Data formulation which does not entail the Green’s function of the background and applied to conventional imaging algorithms to improve their numerical efficiency and accuracy as well.

Bio: Özgür Özdemir is currently associate professor of Electronics and Communication Engineering at Istanbul Technical University  (ITU).  She  received BS and MS degrees from Istanbul Technical University, in 1998 and 2000, respectively and Ph.D. degree in electrical engineering from New Jersey Institute of Technology (NJIT) in 2005.  She then joined  Centre de Mathématiques Appliquées (CMAP), Ecole Polytechnique as a postdoctoral fellow. In 2008, she has returned back to  ITU as a faculty member of Department of  Electronics and Communication Engineering.  She is currently conducting research on microwave and acoustics imaging techniques for medical imaging, through wall imaging radar, antenna design and  thermoacoustic imaging for breast cancer detection.
