Portuguese Abstract: In this work we study theoretically the photonic band gap spectra for a one-dimensional quasicrystal made up of SiO2 (layer A) and a metamaterial (layer B) organized following the Octonacci sequence, where its nth-stage Sn is given by the inflation rule Sn ¼ Sn1Sn2Sn1 for n 3, with initial conditions S1 ¼ A and S2 ¼ B. The metamaterial is characterized by a frequency dependent electric permittivity εðuÞ and magnetic permeability mðuÞ. The polariton dispersion relation is obtained analytically by employing a theoretical calculation based on a transfer-matrix approach. A quantitative analysis of the spectra is then discussed, stressing the distribution of the allowed photonic band widths for high generations of the Octonacci structure, which depict a self-similar scaling property behavior, with a power law depending on the common in-plane wavevector kx
