Abstract

The band structure has been calculated for a two-dimensional photonic crystal consisting of infinite cylindrical openings filled with a resonance gas and forming a square lattice in a dielectric matrix. An additional narrow transmission band close to the edge of the band gap has been detected, along with an additional band gap in the continuous spectrum of the photonic crystal. The novel dispersion properties substantially depend on the fraction of resonance gas in the photonic crystal, as well as on the density of the resonance gas and the position of the resonance frequency relative to the edge of the band gap.
