Prof. Özgür Özdemir\, Istanbul Technical Uni versity\n\nTopic: "Microwave Imaging in Layered Media"\n\nLocation: Middle East Technical University\, Ankara\, Turkey\n\nAbstract: Microwave imagin g of buried targets in inhomogeneous/layered media have been a very import ant research area due to its wide range of applications: biomedical applic ations\, through wall surveillance\, nondestructive testing in material sc ience\, etc. Most of the developed imaging methods require the knowledge o f the background Green’s function which may be very costly. This is part icularly the case for non-smooth-interfaced and/or stratified media where the Green’s function can only be calculated numerically. This would dram atically increase the computational cost of the methods and therefore cons titutes one of their main drawback for this background configuration.\n\nI n this talk\, we will present our recent work on efficient microwave imagi ng techniques for layered medium problems. We have developed a new formula tion of the scattering problem\,i.e\, Cauchy Data formulation which does n ot entail the Green’s function of the background and applied to conventi onal imaging algorithms to improve their numerical efficiency and accuracy as well.\n\nBio: Özgür Özdemir is currently associate professor of Ele ctronics and Communication Engineering at Istanbul Technical University (I TU). She received BS and MS degrees from Istanbul Technical University\, i n 1998 and 2000\, respectively and Ph.D. degree in electrical engineering from New Jersey Institute of Technology (NJIT) in 2005. She then joined Ce ntre de Mathématiques Appliquées (CMAP)\, Ecole Polytechnique as a postd octoral fellow. In 2008\, she has returned back to ITU as a faculty member of Department of Electronics and Communication Engineering. She is curren tly conducting research on microwave and acoustics imaging techniques for medical imaging\, through wall imaging radar\, antenna design and thermoac oustic imaging for breast cancer detection.\n\nAnkara\, Ankara\, Türkiye LOCATION:Ankara\, Ankara\, Türkiye ORGANIZER:ozergul@metu.edu.tr SEQUENCE:0 SUMMARY:[Legacy Report] IEEE AP/MTT/EMC/ED TURKEY CHAPTER SEMINAR SERIES -- SEMINAR 16 URL;VALUE=URI:https://events.vtools.ieee.org/m/154283 X-ALT-DESC:Description: <br /><p>Speaker: Assoc.
