Abstract

The focus behaviors of electromagnetic wave through two-dimensional (2D) high-symmetry photonic quasicrystals (PQCs) have been investigated by using exact multi-scattering numerical simulation. We have found that the high-symmetry PQC flat lenses possess universal feature for non-near-field focus of two kinds of polarized waves. That is to say, the non-near-field focus for two kinds of polarized waves can be realized by using these flat lenses, which are consisting of 12-fold, 10-fold and 8-fold 2D PQCs with the same structures and parameters. Such a superior feature originates from higher rotational symmetry and negative refraction in the PQCs. Thus, potential applications of such a phenomenon to optical devices can be anticipated.
