Abstract:

The discretization of Maxwell's equations using finite difference time domain (FDTD) methods produces real-space-time equations that scale linearly with the system size, N. We present such an order-N scheme adapted to frequency-dependent dielectric functions from which we extract the effective response of metallic structures.
