Abstract :
The unconditionally stable alternating-direction-implicit finite-difference time-domain (ADI-FDTD) method is extended to model multispecies dispersive media for simulation of nanoscale three-dimensional metallic structures based on optical plasmon resonances. Examples involving modeling of Au nanoparticles show that the proposed ADI-FDTD yields improved computational performance versus standard FDTD in highly refined grids and for moderate Courant numbers
