摘要

In this work we consider an electromagnetic system composed of two flat perfectly conductor surfaces and a periodic array of circular inclusions forming a photonic crystal waveguide. A numerical integral method was applied to determine the band structure of the system and the intensity of field of its electromagnetic modes. We found tha t the variation of the filling fraction allow s to control at a certain degree the photonic band structure of the system. We also found interesting band structures that contain regions of nearly zero - dispersion and bandgaps. Although initially we considered that the medium inside the waveguide is vacuum, we also discuss the case of a dispersive metamaterial medium. Some numerical results show the presence of a plasmonic surface mode in the proposed system for TE polarization.
