| Abstract: | People pay much interest to the negative index materials due to the special characteristics, in tins paper, the principle and unique characteristics of negative refraction are introdued. The three ways to realize negative refraction that are from double negative medium to negative refraction, from left-handed medium to negative refraction, and from photonic crystals to negative refraction are expeounded deeply. The practicability of achieving negative refraction of low losses at the optical frequecy bands and the large importance of nanotechnology are analyzed. |
