Abstract
The propagation of electromagnetic (EM) waves in two-dimensional triangular-lattice photonic crystals (PCs) is investigated through dispersion characteristics analysis and numerical simulation of field pattern. We examine different surface terminations of the PC slab for getting a high-quality image. In the lowest photonic band both the TM and TE polarized EM waves can undergo negative refraction and imaging effect even at frequencies above the light line. The dependence of the image on the object distance and sample thickness is also discussed.
