pp: 286-288Experimental Investigation of Relationship between the object- and Image DistanceKun Ren, Xiaobin Ren, Xiangdong Zhang, Zhifang Feng, Zhi-Yuan Li, and Daozhong Zhang doi:10.2529/PIERS061211014939 Downloads: 1141 Abstract:We experimentally investigate the focusing properties of a triangular two-dimensional photonic crystals of which all the cylinders are coated. The relationship between the location of object and image point is analyzed. It's demonstrated that at a certain frequency with relative refractive index of -1, the position of image point obey the geometric-optics analysis and non-near-field imaging can be achieved.References:1.
