Abstract

The far-field focusing properties of two dimensional photonic crystals based flat lens with rod-type honeycomb lattice are investigated using finite difference time domain (FDTD) method. The results match the wave-beam negative refraction law with relative refractive index of -1. But, the image qualities are limited by low transmission at large incident angles. To improve the image qualities, the effects of interface on the far-field image in a two-dimensional honeycomb photonic crystal are investigated. It is found that the image qualities can be improved by modifying the radius of rod near the surface of photonic crystals slab.
