Seminar: Computational Electromagnetics with the FDTD Method for Advanced Propagation and Scattering Applications

Seminar by Dr Panagiotis Kosmas, King's College London

14:00 - 15:00, 12th May 2011, Room: M4.13 CPD Room, Merz Court

Accurate prediction of the propagation and scattering mechanisms of electromagnetic (EM) waves in complicated environments is a key issue for the study of various important real-life problems in imaging, telecommunications and healthcare. This presentation will first introduce one of the most powerful numerical methods for simulating the interactions of EM waves in complex environments, which is known as the finite difference time domain (FDTD) method. We will present examples of applying the FDTD to biological tissue modelling, subsurface sensing, antenna design, and UWB propagation in urban environments. We will also discuss advanced applications such as microwave imaging, where computational EM tools are combined with signal processing and optimization methods for medical diagnosis. A particular example is breast cancer detection, where we have focussed much of our past research efforts.
Panagiotis Kosmas received the Diploma in Electrical and Computer Engineering from the National Technical University of Athens, Greece in 1999, and the M.S. and Ph.D. degrees in Electrical Engineering from Northeastern University, Boston, USA, in 2002 and 2005, respectively. From April 2005 to January 2006, he was a Research Associate at the Wireless Communications Research Group at Loughborough University, UK. He was appointed a Lecturer at the Department of Electronic Engineering, King's College London, in February 2007. From March 2007 to February 2008, he was also a Visiting Scholar at the Computational Electromagnetics Group, University of Wisconsin-Madison, USA, on leave from King's College. Dr Kosmas' current research interests include microwave and UWB technologies with applications to medical imaging, subsurface sensing, telecommunications and healthcare.
