Electric and Magnetic Dispersion for FDTD (Cael Warner)

Video produced by Cael Warner as assignment 7 of UBC Course ENGR 459 Advanced Electromagnetics. Please note that in the derivation of the permeability drude model, there was a mistake using m at first in the dynamic equation, modified to qm though left unmentioned in the video. This is the differential equation for permeability.
mx"+y*m*x' = q_m * H
