Dr. Kofi EDEE was born in Lomé (Togo) in 1975. He received his Ph. D in computational physics for electromagnetic modeling, from Blaise Pascal University (Clermont Ferrand, actually University Clermont Auvergne ). After postdoctoral training in the Microelectronics Technology Laboratory at Grenoble, he returns to Clermont-Ferrand where he currently is Associate professor. He also serves as Director of the Non Destructive Testing department. His research interests concern essentially mathematical and computational physics. More specifically, he develop advanced and accurate electromagnetic modal methods to treat optics and electromagnetic problems for modern nanophotonic devices as plasmonic lenses, waveguides, gratings, etc. He recently introduced a polynomial modal method based on Gegenbauer polynomial expansion and emphasized that the main advantage of this new method is that the continuity relations of the electromagnetic field
can be written in an exact manner.
