Fast Large-Scale Algorithm for Electromagnetic Wave Propagation in 3D Media

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
