报告简介：
In this talk, a fast explicit and unconditionally stable FDTD method will be presented. In this method, a patch-based single-grid representation of the FDTD algorithm is developed to facilitate both theoretical analysis and efficient computation. This representation results in a natural decomposition of the curl-curl operator into a series of rank-1 matrices, each of which corresponds to one patch in a single grid. The relationship is then theoretically analyzed between the fine patches and unstable modes, based on which an accurate and fast algorithm is developed to find unstable modes from fine patches with a bounded error. These unstable modes are then upfront eradicated from the numerical system before performing an explicit time marching. The resultant simulation is absolutely stable for the given time step irrespective of how large it is, the accuracy of which is also ensured. In addition, both lossless and general lossy problems are addressed in the proposed method. The advantages of the proposed method are demonstrated over the conventional FDTD and our previous explicit and unconditionally stable FDTD methods by numerical experiments.

In September 2005, she joined Purdue University, West Lafayette, IN, as an Assistant Professor with the School of Electrical and Computer Engineering, where she became a tenured Associate Professor in 2009, and a Full Professor in 2013.She has authored over 260 papers in refereed journals and international conferences.
Prof. Jiao received the 2013 S. A. Schelkunoff Prize Paper Award of the IEEE Antennas and Propagation Society. She was among the 21 women faculty selected across the country as the 2014-2015 Fellow of ELATE at Drexel, a national leadership program for women in the academic STEM fields. She was one of the 85 engineers selected throughout the nation for the National Academy of Engineering’s 2011 US Frontiers of Engineering Symposium. She was the recipient of the 2010 Ruth and Joel Spira Outstanding Teaching Award, the 2008 National Science Foundation (NSF) CAREER Award, the 2006 Jack and Cathie Kozik Faculty Start up Award, a 2006 Office of Naval Research (ONR) Award under the Young Investigator Program, the 2004 Best Paper Award presented at the Intel Corporation’s annual corporate-wide technology conference (Design and Test Technology Conference), the 2003 Intel Corporation’s Logic Technology Development (LTD) Divisional Achievement Award, the Intel Corporation’s Technology CAD Divisional Achievement Award, the 2002 Intel Corporation’s Components Research the Intel Hero Award (Intel-wide she was the tenth recipient), the Intel Corporation’s LTD Team Quality Award, and the 2000 Raj Mittra Outstanding Research Award presented by the University of Illinois at Urbana-Champaign. Prof. Jiao has served on a number of Technical Program Committees of premium conferences, and editorial boards of journals in electromagnetics, microwave, and circuits. Prof. Jiao was elevated to IEEE Fellow for contributions to computational electromagnetics (Class of 2016).
