Photonic crystal is composed with two different dispersive metamaterials negative refractive index materials. Transmission spectra are obtained by transfer matrix in microwave region. When two materials all are double negative, band structure is the same for TE and TM wave at the same incident angle, which is insensitive to the incident angle. For the one with negative permittivity and positive permeability and another with the double negative, Band gap gets wide as the incident angle increases for TE wave. However, band gap remains when the incident angle is larger than 0.5 rad for TM wave. According to the results, band gap of this photonic crystal can be act as omnidirectional reflector.
