Abstract
Imaging characteristics of germanium cylinder-based decagonal photonic quasicrystal flat lens have been analyzed with respect to width. The results show that the complex near-field scattering effects and the short-range interactions do not determine the occurrence of the imaging phenomenon but affect imaging characteristics. Changing the width will affect the imaging characteristics of the flat lens. As the width increases, the image power, the image quality, and the summed object–image distance change non-monotonically but stabilize gradually.
