Abstract

We report a hemispherical-shaped hyperlens with subwavelength resolution less than $100\mathrm{nm}$. Simulations with the finite-element method show that with a $365\mathrm{nm}$ illumination, the hemispherical hyperlens isotropically magnifies the image along the radial direction. Under linearly polarized light, portions of an object can be resolved. A complete image of the object can be generated by superposing sufficient number of images obtained with incident light in different polarization directions. Such a hyperlens has great potential for realization of nanoscale imaging.
