Random nanostructures of two-dimensional silver dendritic cells are prepared on the flexible Indium Tin Oxides film using the electrochemical deposition method at 0~2 ℃. The Polyvinyl Alcohol film, acted as a dielectric medium, is coated on the silver dendritic cells and combined with the uncoated cells face-to-face to fabricate a Ag/Polyvinyl Alcohol /Ag configuration. This dendritic nano-assembled Ag/Polyvinyl Alcohol/Ag configuration reveals a multiband resonance and different transmission peaks at optical frequencies, while the several contrast samples fail to show any transmission peaks at the same frequencies. The focused points are present when the wavelengths utilized are corresponding to the peaks of the transmission spectrum for the Ag/Polyvinyl Alcohol /Ag configuration.
