Fast Integral Equation Methods in Engineering Design: From Global Maxwell Tomography and Ultimate Bounds for MRI Coil Performance to Quantum Fluctuations Abstract: Advances in computational science are revolutionizing science and engineering. It is clear that in many modern applications, off-the-shelf numerical solvers fail to meet the ever-increasing requirements for ultra-fast computations. The drive for nextgeneration biomedical applications, e.g. high-field magnetic resonance imaging (MRI) and deep brain stimulation, poses some very challenging problems in numerical modeling. Another characteristic example comes from the modeling of fluctuation-induced EM phenomena including thermal radiation, heat transfer, Casimir forces, spontaneous emission, fluorescence, and Raman processes. In my talk, I will briefly describe a new class of volume integral equation methods that offer an ideal platform for customized fast algorithms, where maximal use of a specific setting is possible. The volume integral equation solver together with a series of modern numerical linear algebra algorithms can be seamlessly integrated in a general computational framework for addressing a wide range of challenging applications in MRI device optimization as well as in electrical properties mapping based on MR measurements. I will close my talk by presenting some new volume integral equationbased matrix-trace formulas for the analysis of fluctuation-induced phenomena together with some fundamental limits to optical response in absorptive systems. CV Athanasios G. Polimeridis was born in Thessaloniki, Greece, in 1980. He received the Diploma and the Ph.D. degrees in electrical and computer engineering from the Aristotle University of Thessaloniki, Greece, in 2003 and 2008, respectively. From 2008 to 2012, he was a Postdoctoral Research Associate with the Laboratory of Electromagnetics and Acoustics, Ecole Polytechnique Fédérale de Lausanne, Switzerland. From 2012 to 2015, he was a Postdoctoral Research Associate at the Massachusetts Institute of Technology, Cambridge, MA, USA, where he was a member of the Computational Prototyping Group. Since 2015 he is an Assistant Professor at Skolkovo Institute of Science and Technology, Moscow, Russia. His research interests revolve around computational methods for problems in physics and engineering (classical electromagnetics, fluctuation-induced electromagnetic phenomena, magnetic resonance imaging, and inverse scattering), with an emphasis on the development and implementation of integral-equation-based algorithms. Dr. Polimeridis was awarded a Swiss National Science Foundation Fellowship for Advanced Researchers in 2012.
