Abstract

We report the imaging properties of a two-dimensionalrectangular-lattice photonic crystal (PC) slab consisting of rectangularmetallic rods immersed in a dielectric background. By simulating theelectromagnetic wave propagation through such a PC slab with thefinite-difference time-domain method, we find that a point source placedin the vicinity of the PC slab can form a good-quality image through theslab. The frequency region where a good-quality image is formed can becontrolled by choosing the direction along which the PC slab surfacenormal is placed.
