Dynamical electric dipole theory for quantitatively describing coupled split-ring resonators
Yong Zeng, Douglas H. Werner
Metallic split-ring resonators possess dominant electric dipoles as well as considerable magnetic dipoles under proper excitations. Full-wave numerical approaches are frequently em…

A lossless metamaterial with tunable permittivity and its application as a compact phase shifter
Yong Zeng, Qi Wu, Douglas H. Werner
In this Letter, we propose a new type of lossless metamaterial whose effective permittivity is tunable from negative to positive values. Its optical response is studied analyticall…
