Newmark-FDTD Formulation for Modified Lorentz Dispersive Medium and Its Equivalence to Auxiliary Differential Equation-FDTD with Bilinear Transformation

<p>1D FDTD simulations for different sets of modified Lorentz parameters. (a) All FDTD formulations are stable. (b) Only ADE-FDTD is unstable. Legends are the same as Figure <a href="../fig1/">1</a>.</p>
