This dissertation is devoted to the study of photonic crystals in one dimension. The structure under analysis is a ternary stack dielectric-dielectricmetal and here it is named Metallo-Dielectric Photonic Crystal (MDPC). A brief review of the pure Dielectric Photonic Crystal (DPC) is given for establishing a context and comparing the results of this research. The quarter-wave stack is the core of all the discussion along the manuscript and the key equivalent analytical expressions are derived for the MDPC, such as the dispersion relation, maximum absorption, band diagrams and band gap width, in the case of normal incidence. Also, for the MDPC the region of validity of the band structure is defined comparing it with the transmittance. Then, some of these results are extended for the condition of oblique incidence, calculating formulas for the transversal electric and magnetic modes. The transfer matrix methodology was used in all the investigation.
