Representation of Electromagnetic Responses in Time Domain Using State Space System Identification Method
Speaker: Prof. Krishna Naishadham (School of Electrical and Computer Engineering, Georgia Institute of Technology, Atlanta, Georgia, USA)

Location: Room “Maxwell” (DET conference room, Cittadella Politecnica, 5th floor)
This seminar presents a control system methodology based on system identification to derive state matrices and system dynamics for the extrapolation of simulated time-domain electromagnetic (EM) responses using both input and output data. The method is applied to model transient responses for a dielectric resonator and a wideband slot antenna computed by the finite integration method (CST Microwave Studio) using non-Gaussian excitation pulses typically employed in digital signals. Using state space system identification formulation, a compact representation of the output time-domain signal is derived, including the early-time transient responses, and its numerical implementation depicts no instability (oscillations) in late-time responses plotted well beyond the steady state. Furthermore, all the system poles are found to lie within the unit circle in the complex plane. Excellent model corroboration is achieved with independently computed frequency domain data or measured results. Application of the state space method to improve efficiency in FDTD simulations will also be presented with an example on a printed antenna and a bandpass filter

Benchmarking computational electromagnetics with exact analytical solutions of canonical electromagnetic scattering problems
Speaker: Prof. Danilo ERRICOLO (University of Illinois at Chicago, Chicago, U.S.A.)
Date: 11 September 2017 @ 16:00
Location: Room OFEK – Polo Scientifico F. Ferrari – Povo
Solutions of canonical electromagnetic scattering problems may be used to benchmark computational electromagnetics methods. While the list of known exact analytical solutions is limited, this list extends significantly beyond classical solutions for the scattering from metallic bodies such as the sphere, the 2D metallic wedge, and the infinite circular cylinder. In fact, recently developed exact solutions exist for geometries involving cavities, sharp edges, apertures, and propagation across different media. Unfortunately, many articles discussing computational electromagnetics solutions frequently propose validations or benchmarks with geometries as simple as a sphere and then jump into comparisons with very complex objects such as a numerical model of an airplane. In such cases, validations with simpler, but yet challenging benchmarks should provide additional evidence of their accuracy. In many cases, comparisons with exact solutions for benchmarking purposes are quite straightforward to implement.
Danilo Erricolo received the Laurea degree of Doctor (summa cum laude) in electronics engineering from the Politecnico di Milano, Milan, Italy, in 1993, and the Ph.D. degree in electrical engineering and computer science from the University of Illinois at Chicago (UIC), Chicago, IL, USA, in 1998. In 2009, he was an Air Force Faculty Fellow with the Air Force Research Laboratory, Wright Patterson Air Force Base, Dayton, OH, USA. He is currently a Professor with the Department of Electrical and Computer Engineering, UIC, where he is also the Director of the Andrew Electromagnetics Laboratory and an Adjunct Professor of bioengineering. He developed a 2-D simulator for the propagation of the electromagnetic field in urban environments that could consider base-stations located below or above the average rooftop height, thanks to introduction of uniform theory of diffraction double wedge diffraction coefficients. He contributed to the development of many exact solutions of canonical scattering problems, which advance the understanding of scattering from analytically treatable geometries and provide benchmarks for computational electromagnetics software. As part of these studies, he wrote software for the computation of Mathieu functions that has applications beyond the field of electrical engineering. He also developed an acceleration method for series expansions containing Mathieu, prolate, and oblate spheroidal functions, which impacts all applications of these functions, such as in porous media flow. He contributed to the validation of the incremental theory of diffraction by developing comparisons with exact canonical solutions and experiments. He also applied his research to medical applications, specifically in the field of magnetic resonance imaging. He co-authored the first papers on RF tomography for applications to subsurface sensing and is currently engaged with its extension to other environments. He has authored or co-authored more than 240 publications in refereed journals and international conferences. His current research interests include electromagnetic propagation and scattering, highfrequency techniques, wireless communications, electromagnetic compatibility, the computation of special functions, and magnetic resonance imaging. Dr. Erricolo is a member of Eta Kappa Nu and was an elected full member of the U.S. National Committee (USNC) of the International Union of Radio Science (URSI) Commissions B, C, and E. He served as the Chair from 2009 to 2011, the Vice Chair from 2006 to 2008, and the Secretary of the USNC-URSI Commission E on Electromagnetic Environment and Interference from 2004 to 2005. From 2009 to 2014, he served as the Chair of the USNC-URSI E. K. Smith Student Paper Competition. He also served as the Vice-Chair of the Local Organizing Committee of the XXIX URSI General Assembly, held in Chicago, in 2008. He serves as a member at Large of USNC-URSI from 2012 to 2017, a committee of the U.S. National Academies. He was the General Chairman of the 2012 IEEE International Symposium on Antennas and Propagation and USNC-URSI National Radio Science Meeting, held in Chicago, in 2012. From 2011 to 2016, he was the Chair of the Chicago Joint Chapter of the IEEE Antennas and Propagation Society (AP-S) and the IEEE Microwave Theory and Techniques Society. Since 2005, he has been serving the IEEE AP-S Future Symposia Committee, and since 2006, he has been serving as a USNC-URSI Representative on the AP-S/USNC-URSI Joint Meetings Committee. He was an elected member of the Administrative Committee of the IEEE AP-S from 2012 to 2014 and served as the Chair of the Distinguished Lecturer Program of the IEEE AP-S from 2015 to 2016.

Meta-Atoms for 3D Printing Metamaterials
Prof. Yiannis Vardaxoglou, Fellow IEEE
Head of the Wireless Communications Research Group
Loughborough University, UK
Date: Thursday 14/09/2017 at 3.00 pm
Venue: Room “Nyquist” (DET meeting room, Cittadella Politecnica, 4th floor)
In this seminar, Prof. Vardaxoglou will introduce the concept and uses of MeTa-Atoms (MTAs) in electromagnetic and egineered metamaterials. MTAs are meso scale inclusions in a host material. These meta-atoms could be varied in constitution and geometry to augment a variety of artificial and novel magneto-dielectric properties. Various 3D-printed multi-layered metamaterials with different periodicities fo dielectric or metallic inclusions will be shown. The effect of the periodicity (space between adjacent elements) on the effective metamaterials properties is examined by placing the 3D-printed samples in a waveguide simulator or on a resonator measuring system. Some of these structures have already been applied in engineering applications such as antennas, microwave lenses and electronic devices.
Yiannis Vardaxoglou is the Head of the Wireless Communications Research Group (WiCR) researching wide- ranging topics applicable to cutting-edge wireless communications technology. His research focuses primarily on metamaterial structures for electronic devices, antennas in microwave and mm-wave engineering. He has authored 300 publications and several book chapters and a pioneering book on Frequency Selective Surfaces. WiCR collaborates with many internationally leading universities and companies and is home to the internationally renowned Loughborough Antennas & Propagation Conference (LAPC).
