Abstract

Constant horizontal wavenumber approach is a simple method to model periodic boundary conditions (PBC) in the finite-difference time-domain (FDTD) method proposed for efficient analysis of periodic structures, however, it requires execution of the FDTD simulations many times, each time for a different value of horizontal wavenumber, to achieve useful results. In this contribution we present an implementation of the FDTD/PBC algorithm using the Compute Unified Device Architecture (CUDA) to run the simulations on graphics processor unit (GPU) devices to speed-up the FDTD/PBC simulations.
