Negative Dielectric Constant Material Based on Ion Conducting Materials

NASA Langley Research Center has developed a novel negative dielectric constant material based on ion-conducting materials. A negative dielectric constant material is an essential key for creating metamaterials, or artificial negative index materials (NIMs). NIMs have generated great attention due to their unique and exotic electromagnetic properties, and could be used for unique optical and microwave applications, including new methods of electromagnetic cloaking and extremely lowloss communications.
