If the angular frequency of an electric driving field becomes much larger than the inverse of the scattering time, the response of the electron gas is dominated by the inertial response of the electrons and independent of the scattering time. We are approaching this limit in this preset. Try values of the frequency a factor of three larger and lower than the preset values and use the graph to observe the effect on the phase of the electron response (x-component in blue, y-component in green) relative to that of the driving field (the red curve). (The temperature has been lowered to reduce the Johnson noise.)
