Energy and momentum in negative refractive index materials

The previous chapter has extensively addressed properties of media exhibiting a negative permittivity and permeability, and has led us to revisit some of the most common effects of refraction, radiation, and propagation. In this chapter, we return to a somewhat more theoretical topic: the propagation of energy in left-handed media, with its immediate counterpart, the transfer of momentum from the propagating electromagnetic wave to matter and the traversal of pulses through such media.
