We deposited Al film on the top layer of SiO₂ nanospheres opal using glancing angle deposition (GLAD) method. We found the reflection spectrum of aluminum decorated opal had asymmetric line-shape, that revealed features like double Fano-resonance. We present our results of systematic on this phenomenon.
