520		a Photonic crystal (PhC) lenses with negative refractive index have attractedintense interest because of their application in optical frequencies. In thispaper, 2-D PhC lenses with triangular lattice of cylindrical holes in dielectricmaterial are investigated. Variant physical parameters of the lens are introducedand their effects on the lens response are studied in detail. The effect ofthe surface termination is investigated by analyzing the power flux within thePhC structure. A new lens formula has been obtained which shows a linearrelation between source distance (distance between the source and the lens)and image distance (distance between the image and the lens) for any surfacetermination of the PhC lens. It is observed that the excitation of surfacewaves does not necessarily pull the image closer to the lens. The effects of thethickness and the lateral width of the lens are also analyzed.
