Abstract:
A study for the performance of the Sunflower (circular symmetric structure) quasi-periodic photonic crystal superlens is presented. A series of parameters, including thickness, refractive index and duty cycle, of the Sunflower structure are discussed. The analysis of this study illustrates that the Sunflower structure could provide excellent focusing imaging due to its good circular symmetry and also have negative refraction in low refractive index materials. It provides an important way to choose an alternative to positive refraction lenses in the future.
