I implemented a time-dependent material in my FDTD setup. The material is similar to the one used in this example<\/a>, i.e., stepindex material. I was trying to plot the displacement field or polarization density (D = eps0*epsr*E = eps0*E+P) at a specific point in the time-dependent material as a function of time. Nonetheless, I could not find any monitor or group analysis that shows the time dependency of epsr or D. If I can extract either the permittivity profile or the displacement field vs time (even at a single point), I can ensure that my time-dependent material follows the profile that I intended. Briefly, I am looking for a way by which I can plot the permittivity vs time like the following (from this example<\/a>):<\/p>\n
