Electromagnetic Modeling with GPUs

Modeling electromagnetic (EM) fields and their interaction with a complex environment is important for developing safe and effective wireless systems. Methods for electromagnetic modeling are com-putationally intensive, and even small scenario can have long run times. Developments in graphics processing units (GPUs) over the past decade have created an attractive architecture for scientific com-puting, and many computational methods for EM apply. This paper will give an overview of GPU architecture and history, will briefly de-scribe the field of EM modeling, will summarize past efforts to model electromagnetics using GPUs, and will conclude by considering Finite-Difference Time-Domain (FDTD) and the Parabolic Wave Equation (PWE) on GPUs
