Practical electromagnetic problems usually involve complex geometry with many features that are of significant different scale of characteristic dimensions. Conventional conformal numerical methods, although elegant in theoretical settings, fall short to address such challenges satisfactorily. We have been pursuing non-orthodox approach, non-conformal numerical methods, and are able to achieve remarkable progress to date. In this talk, I shall discuss briefly a few of our recent developments. They are:

*Non-conformal and non-overlapping domain decomposition methods.  

*A novel non-conformal embedded domain decomposition method.

*Surface integral equation discontinuous Galerkin (IEDG) formulation with hyper-singular kernels employing the newly developed reverse operation self-consistent evaluation (ROSE) method.

*Generalized impedance boundary conditions in surface integral equation (SIE) for modeling multi-layer complex material coatings. 

*Computational Intelligence: Gaining physical/engineering insights from simulations.

More importantly, I will also use this talk to advocate bringing electromagnetic back into simulations. Namely, to show how simulation can help us to understand the physics and to analyze the underlying electromagnetic phenomena of the device-under-test.
 

Biography:

Jin-Fa Lee received the B.S. degree from National Taiwan University, in 1982 and the M.S. and Ph.D. degrees from Carnegie-Mellon University in 1986 and 1989, respectively, all in electrical engineering. From 1988 to 1990, he was with ANSOFT Corp., where he developed several CAD/CAE finite element programs for modeling three-dimensional microwave and millimeter-wave circuits. From 1990 to 1991, he was a post-doctoral fellow at the University of Illinois at Urbana-Champaign. From 1991 to 2000, he was with Department of Electrical and Computer Engineering, Worcester Polytechnic Institute. He joined the Ohio State University at 2001 where he is currently a Professor in the Dept. of Electrical and Computer Engineering. Prof. Lee is an IEEE fellow and was serving as an associate editor for IEEE Trans. Antenna Propagation from 2008 to 2013. Prof. Lee is the conference co-Chair of the ACES Conference, 2012, at Columbus. He was an IEEE APS Distinguished Lecturer from 2012 to 2014. Prof. Lee is one of the co-authors of the 2014 Sergei A. Schelkunoff Prize Paper Award and is the recipient of the 2016 Harrington-Mittra CEM award from IEEE AP Society.
