Global Photonic Band Gaps in Two-Dimensional Metallic Lattices
نویسندگان
چکیده
The fundamental and higher frequency global photonic band gaps are obtained for transverse electric (TE) and transverse magnetic (TM) modes in photonic band gap (PBG) structures consisting of two-dimensional (2D) square and triangular lattices of perfectly conducting cylinders. The global photonic band gaps in metallic lattice, which are found to differ qualitatively as well as quantitatively from those in dielectric lattices, not only explain the observations of single-mode confinement and high mode selectivity in recent microwave PBG experiments, and but also provide a useful guide for the design of metallic PBG-based devices in the future. PACS: 42.70.Qs, 41.20.Jb

The effect of material nonlinearity on the band gap for TE and TM modes in square and triangular lattices
In this article, by using the method of finite difference time domain (FDTD) and PML boundary conditions, we have studied the photonic band gaps for TE and TM modes in square and triangular lattices consisting of air holes in dielectric medium and compared the results. In addition, the effect of nonlinearity of the photonic crystal background on the photonic band gaps and comparison with the re...

We have derived the global band gaps for general two-dimensional ~2D! photonic band gap ~PBG! structures formed by square or triangular arrays of metal posts. Such PBG structures have many promising applications in active and passive devices at microwave, millimeter wave, and higher frequencies. A coordinate-space, finite-difference code, called the photonic band gap structure simulator ~PBGSS!...
متن کاملSymmetry reduction in group 4mm photonic crystals
The size of absolute band gaps in two-dimensional photonic crystals is often limited by band degeneracies at the lattice symmetry points. By reducing the lattice symmetry, these degeneracies can be lifted to increase the size of existing photonic band gaps, or to create new gaps where none existed for the more symmetric structure. Specifically, symmetry reduction by the addition of different di...
متن کاملLarger Two-Dimensional Photonic Band Gaps.
Absolute photonic band gaps in two-dimensional square and honeycomb lattices of circular crosssection rods can be increased by reducing the structure symmetry. The addition of a smaller diameter rod into the center of each lattice unit cell lifts band degeneracies to create significantly larger band gaps. Symmetry breaking is most effective at filling fractions near those which produce absolute...
متن کاملPhotonic band gaps based on tetragonal lattices of slanted pores.
We describe broad new classes of three-dimensional (3D) structures which, when made of silicon, exhibit robust 3D photonic band gaps of up to 25% of the gap center frequency. The proposed photonic crystals are readily amenable to very high precision microfabrication using established techniques such as x-ray lithography and template inversion. Each architecture consists of a set of oriented cyl...
