Electric and magnetic energies within dispersive metamaterial spheres: "Exact analytic expressions for the time-averaged electric and magnetic energies within a negative
refractive index metamaterial sphere, which is irradiated by a plane wave, are presented. The
metamaterial is dispersive and lossy, with both the permittivity and the permeability
frequency-dependent and containing damping terms. The frequency dependence of the magnetic and
electric energies inside the sphere is obtained, and it is found that the highest energies occur in
the frequency range in which the sphere material is left-handed."
