Abstract

A novel explicit method to model Lorentz linear dispersive media with finite difference method are presented. The method shows an explicit method without any modification to the Leap-Frogging scheme. The polarizations of the Lorentz media are convoluted simply in the current density. The numerical results are shown to be competitive accuracy with a conventional method. The codes used in the numerical investigation are available on the GitHub (https://github.com/habe36/Dispersive FDTD).
