Optical properties of two-dimensional inverse photonic structures upon disordering of their unit cell

Transmission frequency spectra of two-dimensional inverse photonic structures constituting a hexagonal packing of cylindrical pores in a non-absorbing matrix have been calculated using the Riccati equation. The dependence of the spectral width of the structure opacity band on the degree of a positional disorder of pores in their unit cell has been investigated for the case where the magnitude of the wave vector of electromagnetic radiation in a matrix is on the order of the pore size.
