摘要

We present a fast, large-scale algorithm for the simulation of electromagnetic waves (Maxwell's equations) in three-dimensional inhomogeneous media. The algorithm has a complexity of O(N log(N)) and runs in parallel. Numerical simulations show the rapid treatment of problems with tens of millions of unknowns on a small shared-memory cluster (≤ 16 cores).
