采用“自下而上”的电化学沉积方法，在透明ITO 玻璃基底上制备了银树枝/二氧化钛/银树枝的复合结构。通过调节工艺，实现了样品在可见光波段由多频透射到单频透射的转变。并且通过改变沉积条件等，可以灵活调节样品的响应频段。制备了在绿光、黄光和红光频段产生响应的3种样品，并测试了绿光频段样品的平板聚焦行为。实验发现，这种特殊的光透射行为和平板聚焦现象是由光波通过复合材料时引起的电磁谐振所致。

In this paper,an Ag/TiO2/Ag composite configuration,of which the Ag has dendrite-like morpholo-gy,was successfully prepared on a transparent ITO glass substrate via the bottom-up electrochemical deposition method.By adj usting the process conditions,the transmission of sample can be altered from multiple frequen-cies 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 wave-lengths.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 configura-tion.
