Simulation of Dispersionless Injections and Drift Echoes
... Whether or not dispersion is seen in the initial rise of the electron flux depends on whether the incoming pulse or the gradient drift dominates the changes in the electron flux. At midnight (or the local time centered on the direction of the pulse arrival) the pulse moves all energy particles inwar ...

Today in Physics 217: conductors
... Since the path is finite, the field within the cavity must be zero. This is why you can shield external electrostatic fields with a conducting box (Faraday cage), and why you won’t get electrocuted if lightning strikes your car while you’re inside. (Unless you drive a Saturn or a Corvette, that is.) ...
