Abstract

A graphics processing unit implementation of the multilevel plane-wave time-domain algorithm for rapidly evaluating transient electromagnetic fields generated by large-scale dipole constellations is proposed. The implementation achieves 50 × speedup and 60%-75% memory reduction compared to its serial CPU implementation.
