Abstract

In this paper, an Ag/TiO2/Ag composite configuration, of which the Ag has dendrite-like morphology, was successfully prepared on a transparent ITO glass substrate via the bottom-up electrochemical deposition method. By adjusting the process conditions, the transmission of sample can be altered from multiple frequencies to single frequency. And the operating frequency of sample can be flexibly tuned via changing deposition process. Three kinds of samples that respectively operate in the region of green, yellow, and red wavelengths were fabricated. In addition, we measured the flat-focusing property of the sample working at green wavelengths. It was found that the unique properties of transmission and flat-focusing phenomenon can be attributed to the electromagnetic resonance induced by the interaction between optical waves and the composite configuration.
