Abstract :
It has been noted in the literature that the power-energy relation for electromagnetic fields may be written in the form of a flow continuity equation, and thereby a velocity of electromagnetic energy flow may be defined. The force-momentum field relation may be used in the same way to define a velocity of momentum flow, and it is shown that the flow velocity for both momentum and energy is the group velocity.
