    "abstract": "We present a detailed study of light propagation in waveguides with\nanisotropic metamaterial cores. We demonstrate that in contrast to conventional\noptical fibers, our structures support free-space-like propagating modes even\nwhen the waveguide radius is much smaller than the wavelength. We develop\nanalytical formalism to describe mode structure and propagation in strongly\nanisotropic systems and study the effects related to waveguide boundaries and\nmaterial composition.",
