Abstract :
A radially anisotropic sphere with certain ranges of hyperbolic permittivity seems to be lossy even when the losses in the material parameters vanish. This surprising effect is present both in the quasistatic polarizability and in the Mie-scattering solution, and both solutions agree in the long-wavelength limit.
