We present a scheme to realize both the zero-n and the zero-ϕ eff gap in a one-dimensional photonic band gap structure containing metamaterials. The frequency dispersion of the effective electric permittivity and magnetic permeability of the metamaterials in the adjacent layers in one period are represented by the Drude model and the resonant model. The chosen structure is composed of alternate double-negative and double-positive layers which exhibit a zero-n gap in a certain frequency range whereas in a higher frequency range it behaves as alternate permittivity negative and permeability negative layers to exhibit a zero-ϕ eff gap. Some properties and benefits of having the zero-n and the zero-ϕ eff gap in the same physical system are discussed.
