  [show abstract] [hide abstract]
  ABSTRACT: We study ray dynamics inside the hyperlens, a device capable of sub-diffraction-limited far-field imaging. An analytical result for the ray trajectories inside the hyperlens is obtained using Hamiltonian optics, which offers an alternative description of the device. It is also found that the ray trajectories can exhibit a unique spiraling nature inside the device. Numerical simulations of plane wave and Gaussian beam scattering from the hyperlens confirm the semiclassical description.

• Article: Slow light and 3D imaging with non-magnetic negative index systems.

  ABSTRACT: We demonstrate that strongly anisotropic planar dielectric systems can be used to create waveguides supporting modes with extremely slow group velocity. Furthermore, we show that such systems can be used for 3D imaging, with a potential for subwavelength resolution.

  Article: Optical Hyperlens: Far-field imaging beyond the diffraction limit.

  Zubin Jacob, Leonid V Alekseyev, Evgenii Narimanov
  [show abstract] [hide abstract]
  ABSTRACT: We propose an approach to far-field optical imaging beyond the diffraction limit. The proposed system allows image magnification, is robust with respect to material losses and can be fabricated by adapting existing metamaterial technologies in a cylindrical geometry.
