Imaging of a point source by a slab of 2D PhC of hexagonal lattice. The interface is normal to the Γ-M direction, and the normalized frequency is . The distance between the source and the first interface is , the distance between the image and the second interface is , and the thickness of the slab is . (a) , (b) , (c) .
