Coupling between Fano and Bragg bands in the photonic band structure of two- dimensional metallic photonic structures

Original language description

The frequency and transmission spectrum of a two-dimensional array of metallic rods is investigated numerically. Based on the recent analysis of the band structure of two-dimensional photonic crystals with dielectric rods [Phys. Rev. A 92, 043814 (2015)], we identify two types of bands in the frequency spectrum: Bragg (P) bands resulting from a periodicity and Fano (F) bands which arise from Fano resonances associated with each of the cylinders within the periodic structure. It is shown that the existence of the Fano band in a certain frequency range is manifested by a Fano resonance in the transmittance. In particular, we reexamine the symmetry properties of the H-polarized band structure in the frequency range where the spectrum consists of the localized modes associated with the single-scatterer resonances and we explore the process of formation of Fano bands by identifying individual terms in the expansion of the linear combination of atomic orbitals states. We demonstrate how the interplay between the two scattering mechanisms affects the properties of the resulting band structure when the radius of cylinders is increased. We show that a different character of both kinds of bands is reflected in the spatial distribution of the magnetic field, which displays patterns corresponding to the corresponding irreducible symmetry representations
