Elsherbeni, “A FDTD scattered field formulation for dispersive media

This summary presents a scattered field formulation for the finite difference time domain technique applied to dispersive media charcterized by Debye equation with two relaxation constants. The 3D formulation is based on the auxilary differential equation (ADE) approach. For verification purposes, numerical results for a one dimensioal problem involving reflections from a dispersive dielectric half-space are presented and compared with the exact solution
