Metamaterials are nano-engineered media with designed properties beyond those available in nature with applications in all aspects of materials science. In particular, metamaterials have shown promise for next generation optical materials with electromagnetic responses that cannot be obtained from conventional media. We review the fundamental properties of… (More)
In this paper we discussed the stability of the null solution of the second order differential equation. Under some unusual assumptions we obtain new stability results for this classical equation.
We report on experimental and theoretical results on EELS from 12nm single-crystal gold films. Our results show that momentum resolution of the electrons gives insight into signatures of non-locality and quantum nature of the excitations.
