In this paper, super-resolution imaging and negative refraction by a two-dimensional (2D) triangular lattices graded photonic crystal (GPC) were studied. The graded photonic crystal (GPC) was obtained by varying the radius in each row so that its effective refractive index changes along the transverse direction. By using Plane Wave Expansion (PWE) method and Finite-Difference Time-Domain (FDTD) method, we show that negative refraction and superlensing can be realized in the designed graded photonic crystal. Numerical simulations show that the photonic crystal structures and frequency have an impact on the resolution.
