Enlarged band gap in photonic heterostructure (PC1/PC2) composed of metamaterials and magnetic materials is studied using simple transfer matrix method. As we know that the meta-materials have the unusual electromagnetic properties having negative refractive index. The negative index material is affected with their optical parameters like refractive index, permittivity, permeability and thickness of the materials. The PC1 and PC2 are two photonic crystals containing NIM with different thickness ratio. When these two PCs are combined and make a heterostructure of PC1/PC2 of different thicknesses ratio, then the band gap of such heterostructure is enlarged due to the band gap of PC1 and PC2. Such structure may be used as a broad band filter for TE and TM modes.
