IX.URSI-TÜRKİYE 2018 BİLİMSEL KONGRESİ ULUSAL GENEL KURUL TOPLANTISI

       Professor of Electrical Engineering and director of the Electromagnetic Communications Laboratory at Penn State University in University Park, Pennsylvania, Raj Mittra has made fundamental contributions to electromagnetics through his research skills and as a mentor to those studying in the field.
His research revolutionized computational electromagnetics, resulting in many antenna, radome, scattering and microwave applications. Dr. Mittra was among the first to recognize the computer's potential for solving large-scale electromagnetic problems. He was also a contributing editor of “Computer Techniques for Electromagnetics,” the first definitive book on computational electromagnetics.
His seminal work on finite-difference time-domain (FDTD) methodology created a number of novel FDTD techniques, such as the conformal FDTD method. In addition, his approach to evaluating the radiation integrals of reflector antennas led to the design of large and complex antennas involving single and multiple reflectors and normal and offset feeds
Dr. Mittra pioneered generalized scattering matrix analysis, which dramatically improved the efficiency and numeral stability of the Moment Method and other techniques for solving integral equations. He is responsible for more than 30 new methods for solving scattering problems, other numerical methods and antenna designs. He also developed original approaches for analyzing scattering by periodic structures.
At Penn State and as a professor in the Electrical and Computer Engineering Department at the University of Illinois, Dr Mittra was an advisor to more than 85 doctoral and 85 master's degree candidates. Many of his students went on to make significant contributions to the fields of antennas, propagation and electromagnetics. He has published 35 books or book chapters. As principal author of “Imaging with Coherent Fields,” he investigated the role of electromagnetic fields in holography, sparking research into microwave holography and significant new directions in inverse scattering and coherent acoustical imaging.
An IEEE Life Fellow, Dr. Mittra is the former president of the IEEE Antennas and Propagation Society and was the editor of IEEE Transactions on Antennas and Propagation. He is President of RM Associates, a consulting organization providing services to industrial and governmental organizations worldwide.
Dr. Mittra received his bachelor’s degree in physics from Agra University in India, his master’s degree in radio physics from the University of Calcutta, and his doctoral degree in electrical engineering from the University of Toronto in Canada.

       Managment of the variability in electromagnetism and in dosimetry in particular Joe Wiart; Chaire C2M LTCI Telecom ParisTech

Thanks to the important progress in high performance calculation, numerical simulations have an increasing role in applied electromagnetics and in particular in numerical dosimetry. Numerical methods such as FDTD are more and more used to design system, antennas and assess performances and quantities such human exposure. With the versatile use of the devices and the increasing complexity of the networks the ”deterministic ” assessment of the human population RF exposure is facing limits with variable configurations and usages. Despite the increasing progress in high performance calculations the computattion time does not often allow to usel Monte Carlo method to handle variablitlity. The design of system is facing similar challenge with the propagation of the uncertainty of the simulation inputs. To overcome such limits and face the challenges new approaches based on statistic have been developped in applied electromagnetism. They aim to built meta-model, having a quick computation time, substituting time consuming calculation methods such as FDTD. Nowadays, in applied electro-magnetics, parsimonious methods such as Planning Experiment, Polynomial Chaos Expansion, Kriging or Low rank tensors approximation are often used to manage variability and performed uncertainty quantification. In this talk we will introduce these methods and we will illustrate them with studies in dosimetry.

EM diffraction is critical in many applications including antennas and propagation. Understanding and visualizing EM wave – object interaction is crucial in designing new antenna systems, in predicting path losses through complex propagation paths, etc. In order to do that wave pieces such as diffracted waves, Fringe waves, etc., should first be studied on canonical structures. Then, complex objects can be investigated by using HFA as well as numerical methods in hybrid form intelligently. EM wave scattering from waves – objects interaction has long been investigated. Interesting wave phenomena, diffraction, occur when objects have sharp edges and tips. Methods known as High Frequency Asymptotics, such as Geometric optics (GO), Physical Optics, (PO), Geometrical Theory of Diffraction, (GTD), Uniform Theory of Diffraction (UTD), Physical Theory of Diffraction (PTD) and Theory of Edge Diffraction (TED) have been successfully applied to variety of EM problems. Recently, numerical methods, such as Finite Difference Time Domain (FDTD), Method of Moments (MoM) and Finite Element Method (FEM) have also been used in modeling EM diffraction. These powerful methods, together with novel approaches, have shown to be successful not only in modeling EM diffraction but also in distinguishing wave pieces such as scattered waves, diffracted waves, Fringe waves, etc., which is very important in visualizing and understanding complex wave – object interaction.
