Abstract: Optical metamaterials(OMs) at visible wavelengths have been extensively developed. OMs reported presently are all composed of periodic structure, and fabricated by top-down approaches. Here, the colored visible light frequencies metamaterials composed of double layer array disordered and geometrical variational dendritic cells are demonstrated, fabricating by a novel bottom-up approach. The experiment demonstrated that the OMs composed of random silver dendritic cells caused the appearance of multiple transmission passbands at red and yellow light frequencies. The slab focusing experiment reveals a clear point image in the range of half-wavelength with an intensity of 5% higher than that of the light source. Proposed colored OMs will open a new way to prepare the cloak and the perfect lens suitable for optical frequency.
