Computational Electromagnetic Simulations

I used finite difference time domain techniques to model the interaction of electromagnetic fields with physical objects and the MRI environment. The simulation models were developed programatically with Python API's to be automated and the simulated results were used to develop verification & validation (V&V) protocols, which are critical components of a quality management system such as ISO/IEC 17025.
