Abstract :
The time domain modeling and simulation of electromagnetic (EM) waves interaction with nanodevices, at high spatial and time resolution, requires high computational power. In this paper we present an implementation of the Hertzian Potential Formulation (HPF) on the Graphics Processing Units (GPUs) through the NVIDIA´s CUDA (Compute Unified Device Architecture)programming model. The results demonstrate that this GPU tool outperforms the CPU based HPF implementation, reaching a speedup from 30× to 70×.
