Computational Electrodynamics: From Metamaterials and particle accelerators to biomedical applications

Share

The emergence of computers in the last century and the surge of computation technology have revolutionized the research progress through advanced simulation tools. Research methodologies based on electromagnetic fields and waves, as the paramount method for investigating novel phenomena, were similarly affected by the simulation technology. The presentation aims to show few of the numerous research schemes where computational electrodynamics is playing a significant supportive role.

Metamaterials and metasurfaces have shown strong promise to scientists and engineers to realize materials with properties not found in nature. One of the outcomes of this research field was metamaterial absorbers, where thin wideband radar absorbers are pursued. Invent of 2D materialsin the last years had shown strong potentials for developing tunable metasurfaces, whose simulation paves the way toward new functioning devices. Particle accelerators is another research domain where electromagnetic fields are applied for transferring energy to particles. The possibility of designing electromagnetic fields to realize Compact accelerators has been the focus of extensive research efforts in the last years. The crucial role played by computational electromagnetics in this area will be reviewed through projects where ultrafast accelerators are designed and implemented. Eventually, the presentation reviews the recent achievements in material characterization and assessment of field interactions with human body using the state-of-the-art methods in computational electromagnetics.

Biography:

Arya Fallahi was born in 1982 and raised in Tehran, Iran. He finished his high school studies as the winner of the Gold Medal in the National Physics Olympiad in 1999. Arya earned bachelor degrees in both applied physics and electrical engineering from Sharif university of Technology in 2004, and completed the master of science degree in electrical engineering at Tehran University in 2006. He then moved to Switzerland, where he worked on electromagnetic properties and applications of metamaterials as a doctoral student. He earned his PhD degree from Swiss Federal Institute of Technology (ETH Zurich) in 2010, winning a prestigious ETH Medal for Outstanding PhD Thesis. After the PhD, he joined the Paul Scherrer Institute (PSI) for a two-year post-doctoral appointment in the Accelerator Modelling and Advanced Simulations (AMAS) group. In 2012, he moved to Germany to work as a computational physicist in the ultrafast optics and X-ray sources group of the Deutsches Elektronen-Synchrotron (DESY), in the Centre for Free Electron Laser Science (CFEL) in Hamburg. He successfully defended his habilitation thesis in 2018 at the University of Hamburg. He joined the IT'IS Foundation as Project Leader for Computational Electromagnetics in January 2019. His experience revolves around applications of computational science and scientific computing in various fields of physics and engineering. He has dedicated his research efforts to topics in electromagnetic metamaterials, computational nano-optics, plasmonics, compact electron accelerators, high-power THz generation, laser physics, free electron laser science, material characterization and bioelectromagnetics.
