Metamaterials with index ellipsoids at arbitrary k-points
Ordinary materials have their index ellipsoids centered at zero momentum. The authors propose a metamaterial of interpenetrating wire meshes whose connectivity can be used to control the number and position of index ellipsoids at arbitrary nonzero k-points. This could provide a new platform for broa...

| Sumario: | Ordinary materials have their index ellipsoids centered at zero momentum. The authors propose a metamaterial of interpenetrating wire meshes whose connectivity can be used to control the number and position of index ellipsoids at arbitrary nonzero k-points. This could provide a new platform for broadband functionality. |
