CST – Computer Simulation Technology

SIMULIA Bioelectromagnetics Day

Join us for an exciting opportunity to learn about the latest developments in 3D bioelectromagnetic (BioEM) simulation. BioEM is relevant to the design of medical systems such as MRI and implanted devices, but also to the analysis of communication devices and other systems that expose the human to EM fields. This workshop aims to give design and research engineers an insight into the latest 3D simulation technology for designing electromagnetic devices and systems for the BioEM and medical market. It will provide opportunities to hear and interact with industry experts.

SIMULIA, Dassault Systèmes office

Eagan, MN, 55122 United States
9 a.m. - 5 p.m.
Date: September 6, 2018
Language: English

Fee: Free of charge
No registration possible.


This presentation will introduce the standardized approach for compliance evaluation of RF exposure from mobile (vehicle mounted) antennas based on FDTD method jointly developed by the IEEE and IEC standards organizations. The basic requirements to model and simulate the relevant exposure conditions and quantify the Specific Absorption Rate (SAR) in human body are fully specified in the two new standards IEC/IEEE 62704-1 and 62704-2 (both published in 2017). This method is now widely accepted as a standard way to demonstrate compliance with international RF exposure safety limits and in certain exposure conditions, especially involving passengers in a vehicle, is the only practical way to derive conservative and reproducible SAR results that helps to avoid costly and in many cases too restrictive electromagnetic field measurements.

Giorgi received the M.Sc. and Ph.D. degrees in radio physics and electronics from Tbilisi State University (TSU), Tbilisi, Georgia, in 1994 and 1998, respectively. Until 2000, he was an Associate Professor at TSU, where he was engaged in research on computational electromagnetics. From 2001 to 2008, he was with Motorola Corporate Electromagnetic Energy Research Laboratory, Fort Lauderdale, FL. He is currently a Distinguished Member of the Technical Staff within the Chief Technology Office at Motorola Solutions, Inc. His research interests are in applied and computational electromagnetics and include antenna technology, numerical techniques and RF exposure and dosimetry. He is actively involved in the IEEE and IEC standards related to human exposure to RF energy and is chairing the working group that developed and standardized the computational methods for evaluation of exposure from mobile radio antennas.


In Magnetic Resonance Imaging, a wide variety of magnetic fields are applied to the human body. They range in frequency from DC to hundreds of MHz, and in strength from a fraction of the earth’s magnetic field to 5 orders of magnitude greater. While they are intended to manipulate specific atomic nuclei throughout the body in order to map their distribution and properties throughout space, their various interactions with the human body also have many other consequences, resulting in adverse effects on the images acquired and concerns for subject safety and comfort. In this talk we will explore some of the ways simulations can be used to gain insight into the complexities of MRI, including consideration of the interactions between the applied fields and the human body, as well as how we can use this information to design better and safer techniques and technology.

Professor Christopher M. Collins first became enamored by electromagnetics and found his way to field simulations for MRI as an undergraduate student. Through the years he introduced many of the available advanced field simulation techniques to the MRI community, and developed methods for interpreting simulation results specific to MRI. He has developed solvers for static magnetic fields and temperature, as well as a complete MRI system simulator considering the complexities of the human body. With more than 20 years of experience in this area, he still finds no shortage of challenging and interesting problems in this exciting, dynamic area.
