Optimum structure of 1D metal-dielectric multiple layered in transparent property.

We investigate the optical properties of 1D metal-dielectric multiple layers made by silver Ag/TiO2 using invariant imbedding method developed by us recently. We study optical properties in both periodic and quasi-periodic generated by Thue-Morse or Fibonacci sequences. In some specific cases, at the edge of band structure the maximum of transmittance achives about 90% when total thickness of all metal layers is about 70nm, while the maximum of transmittance of bulk silver layer is about 5% at large frequency corresponding to small wavelength (320nm). We study also the total thickness of metal increasing about 10% (80nm), but the maximum of transmittance decreases about 5% (85%).
