Abstract

We show the advantages of using inhomogeneous dielectric rods to design photonic crystals that behave as materials with negative refractive index. We found that the analysis of light scattering properties of inhomogeneous dielectric rods allows one to estimate the interval of frequencies where a photonic crystal exhibits negative refractive index. A triangular‐lattice photonic crystal – assembled from multilayer dielectric rods designed to approximate a fish‐eye profile – is shown to exhibit negative refractive index and good focusing properties at frequencies where the fish‐eye dielectric rods scatter the light like a medium with negative refractive index.

## Abstract In the Rapid Research Letter [1] it is shown that a flat array of dielectric rods can act as a focusing lens of good quality – provided the rods have specified gradients of the dielectric constant. This design is superior to conventional photonic crystals (PC) utilizing homogeneous rods
