There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Seminar Title: Modeling of Electrically Large and Wideband Structures
Speaker: Prof. Antonije Djordjevic, University of Belgrade, School of Electrical Engineering, Belgrade, Serbia
Abstract:
The first part of the lecture will present key activities of the Group for Electromagnetics, Antennas, and Microwaves, at the School of Electrical Engineering in Belgrade. The second part will cover two numerical topics in more detail. One topic is a technique for efficient solution of electromagnetically large structures, based on the diakoptic approach, i.e., partitioning of the analyzed system (domain decomposition) into a number of smaller subsystems. On the partitioning surfaces, artificial electric and magnetic currents are placed, which are used to uniquely describe the subsystem with respect to the outer world. The diakoptic technique has been successfully applied to various problems using the method of moments (MoM) alone or in combination with the finite-element method (FEM). Both MoM and FEM involve higher-order approximation functions, thus providing an efficient and accurate algorithm. The second topic deals with a mathematical description of materials in the frequency domain that provides a causal response in the time domain. This description is particularly suitable for dielectrics commonly used in highfrequency applications. Various aspects of the causality and Fourier transform are also tackled.
Speaker Bio:
Antonije R. Djordjević was born in Belgrade, Serbia, on April 28, 1952. He received the
B.Sc., M.Sc., and Ph.D. degrees from the School of Electrical Engineering, University of
Belgrade, in 1975, 1977, and 1979, respectively. In 1975, he joined the School of Electrical
Engineering, University of Belgrade, as a teaching assistant. He was promoted to an
assistant professor, associate professor, and professor, in 1982, 1988, and 1993,
respectively. In 1983, he was a visiting associate professor at Rochester Institute of
Technology, Rochester, NY. Since 1992, he has been an adjunct scholar with Syracuse
University, Syracuse, NY. In 1997, he became a corresponding member of the Serbian
Academy of Sciences and Arts, and he became a full member in 2006. His main area of
interest is numerical electromagnetics, in particular applied to fast digital signal
interconnects, wire and surface antennas, microwave passive circuits, and electromagnetic compatibility problems.
He is an author or co-author of about 230 papers (61 of which were published in leading
international journals), co-author of 3 monographs, 2 chapters in monographs, 9
monographs with software (all monographs published in the USA), and 13 textbooks at the
university level (in Serbian). He has been a reviewer for the IEEE Transactions on
Microwave Theory and Techniques, IEEE Transactions on Antennas and Propagation, and
other journals.
Undergraduate and Graduate students will have opportunity after the talk to have discussions with Prof. Djordjevic.
Sponsored by the Electromagnetics TIA, School of ECE, Georgia Tech.
Co-Sponsored by the IEEE AP/MTT Chapter, Atlanta.
Food and refreshments available after the seminar.
