Paper Abstract

A two-dimensional (2-D) photonic quasicrystal (PQC) flat lens with three scatterers is proposed, and its focusing characteristics for a point source are analyzed for the case of a continuously changing scatterer radius. The results show that a super-lens can be formed by three scatterers, and there is a threshold for scatterer radius. The focusing characteristics of the flat lens within the focusing radius are changed with regularity. It is reported for the first time that best image quality and the stability of perfect imaging in this 2-D PQC flat lens with three scatterers are superior to those in 2-D PQC or periodic photonic crystal flat lenses with multiple scatterers.
