摘要：
The far-field focusing properties of two dimensional rod-type honeycomb lattice photonic crystals are investigated by using finite difference time domain method, and it was found that it explicitly follows 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. The image qualities can be improved by modifying the radius of rods near the surface of photonic crystals slab.
