This study deals with in photonic band gap materials based on metamaterials properties that consist in a periodic set of positive and negative index layers. These structures present new optical properties such as a zero-n gap, zero-phase delay transmission and self-collimation effect. Here, we theoretically demonstrate that self-collimation can be render resonant or combines with slow light regime in photonic band gap metamaterials.
