An Anisotropic Metamaterial Leaky Waveguide
Huikan Liu, Kevin J. Webb
We propose a leaky optical waveguide achieved with a uniaxially anisotropic metamaterial that supports both forward and backward leaky waves. The backward leaky nature is exploited…
Polaritonics in complex structures: Confinement, bandgap materials, and coherent control
David W. Ward, Eric Statz, Jaime D. Beers +6
We report on the design, fabrication, and testing of ferroelectric patterned materials in the guided-wave and polaritonic regime. We demonstrate their functionality and exploit pol…
On the physical origins of the negative index of refraction
David W. Ward, Keith A. Nelson, Kevin J. Webb
The physical origins of negative refractive index are derived from a dilute microscopic model, producing a result that is generalized to the dense condensed phase limit. In particu…
The Role of Multiferroics in the Negative Index of Refraction
David W. Ward, Eric Statz, Kevin J. Webb +1
We explore the possibility of realizing intrinsic far infrared negative index materials (NIM) in multiferroic crystals (crystals simultaneously possessing a ferroelectric and ferro…
