Negative Refraction Using Frequency-Tuned Oxide Multilayer Structure

Abstract EN

An oxide-based multilayer structure was proposed to realize negative refraction.

The multilayer composes of alternative layers having negative permittivity and negative permeability, respectively.

In order to realize negative refraction, their dielectric and magnetic resonances of layers will be tuned to the frequency as close as possibly via changing their temperature, composition, structure, and so forth.

Such oxide-based NIMs are attractive for their potential applications as optical super lenses, imagers, optical cloaking, sensors, and so forth, those are required with low-loss, low-cost, and good fabrication flexibility.
