This thesis presents a three-dimensional metamaterial design composed of a metal-dielectric thin-film multilayer stack. Light propagation in the optical metamaterial can be controlled by the layer geometry. The multilayer design benefits from the numerous fabrication techniques which are readily available to realize multilayer structures. Furthermore, because light is coupled to guided waves in the metamaterial, rather than confined to a localized resonance, absorption losses are reduced. Because of these advantages, the realization of a three-dimensional metamaterial operating in the visible and UV spectral range becomes possible. We demonstrate optical properties that do not exist in natural materials, such as a vanishing permittivity at a specific wavelength of choice, negative refraction of energy leading to a flat lens, and a structure with 100% coupling efficiency while not index matched to its surroundings.
