ELECTROMAGNETIC WAVE PROPAGATION MODELING AND SIMULATION
This IEEE AP-S DL talk will focus on electromagnetic wave propagation which has long been one of the important options for medium and long-range communication as well as radar systems. In addition to the classical LF/MF/HF broadcast and communication systems, emerging HF and VHF radar technologies, intelligent transportation or digital radio broadcast systems require understanding propagation characteristics over the Earth’s surface along realistic propagation paths. It is therefore propagation engineers’ or site surveyors’ dream to have a numerical propagation tool that calculates path losses between any two points marked on their digital maps. This necessitates the solution of electromagnetic (EM) wave equation in three-dimension (3D) which takes into account various EM effects, such as, the irregular terrain profile, the vegetation, the Earth’s curvature, the atmospheric refractivity, the presence of buildings, cars, and other obstacles, etc. Also, it must include all the relevant scattering components (e.g., multiple reflections and refractions, edge/tip diffractions, surface and/or leaky waves, etc.) that account for the path loss. Unfortunately, this is not yet in sight. The aim of this presentation is to review electromagnetic wave propagation models and numerical propagation prediction tools and discuss problems and challenges as well as to project future developments.

ELECTROMAGNETIC WAVE PROPAGATION MODELING AND SIMULATION
Biography:
Prof. Dr. Levent Sevgi is a Fellow of the IEEE. He received his B. Eng., M. Eng., and PhD degrees in Electronic Engineering from Istanbul Technical University (ITU) in 1982, 1984 and 1990, respectively. In 1987, while working on his PhD, he was awarded a fellowship that allowed him to work with Prof. L. B. Felsen at Weber Research Institute / New York Polytechnic University York for two years. His work at the Polytechnic concerned the propagation phenomena in non-homogeneous open and closed waveguides.
He was with Istanbul Technical University (1991–1998), TUBITAK-MRC, Information Technologies Research Institute (1999–2000), Weber Research Institute / NY Polytechnic University (1988–1990), Scientific Research Group of Raytheon Systems Canada (1998 – 1999), Center for Defense Studies, ITUV-SAM (1993 –1998 and 2000–2002) and with University of Massachusetts, Lowell (UML) MA/USA as a full-time faculty (2012 – 2013) and with DOGUS University (2001-2014). Since Sep 2014, he has been with Istanbul OKAN University.
He has been an IEEE AP-S Distinguished Lecturer for the term 2020-2022. He served one-term in the IEEE AP-S AdCom (2013-2015) and one-term and as a member of IEEE AP-S Field Award Committee (2018-2019). He has been the writer/editor of the “Testing ourselves” Column in the IEEE AP Magazine (since Feb 2007), a member of the IEEE AP-S Education Committee (since 2006), He has also served in several editorial boards (EB) of other prestigious journals / magazines, such as the IEEE AP Magazine (since 2007), Wiley’s International Journal of RFMiCAE (2002-2018), and the IEEE Access (2017-2019 and 2020 - 2022). He is the founding chair of the EMC TURKIYE International Conferences (www.emcturkiye.org).
He has been involved with complex electromagnetic problems and complex communication and radar systems for nearly three decades. His research study has focused on propagation in complex environments; electromagnetic scattering and diffraction; RCS prediction and reduction; EMC/EMI modelling, simulation, tests and measurements; multi-sensor integrated wide area surveillance systems; surface wave HF radars; analytical and numerical methods in electromagnetics; FDTD, TLM, FEM, SSPE, and MoM techniques and their applications; bio-electromagnetics. He is also interested in novel approaches in engineering education, teaching electromagnetics via virtual tools. He also teaches popular science lectures such as Science, Technology and Society.
He has given dozens of seminars, invited/keynote talks, organized/presented several tutorials, training sessions and short courses from half-day to three-days in universities/institutes all around the World. He has published more than a dozen special issues / sections in many journals as a guest editor and/or a co-guest editor.
His recent keynote talks are: (i) From Engineering Electromagnetics towards Electromagnetic Engineering: Teaching, Training Next Generations in MMS’2018 Mediterranean Microwave Symposium, Istanbul / Turkey, and in EuCAP 2019 European Conference on Antennas and Propagation, Krakow / Poland, (ii) Radiowave Propagation Modeling and Simulation in APCAP 2019 Asia-Pasific Conference on Antennas and Propagation, Incheon / S. Korea, and (iii) From Design to Market: EMC Engineering in InCAP 2018 Indian Conference on Antennas and Propagation, Hyderabad / India.
He has published many books/book chapters in English and Turkish, over 180 journal/magazine papers/tutorials and attended nearly 100 international conferences/symposiums. His three books Complex Electromagnetic Problems and Numerical Simulation Approaches, Electromagnetic Modeling and Simulation and Radiowave Propagation and Parabolic Equation Modeling were published by the IEEE Press - WILEY in 2003, 2014, and 2017, respectively. His fourth and fifth books, A Practical Guide to EMC Engineering (Sep 2017) and Diffraction Modeling and Simulation with MATLAB (Feb 2021) were published by ARTECH HOUSE.
His h-index is 35, with a record of more than 4100 citations (source: Google Scholar, July 2021).
