Abstract
An increased plasmon resonance frequency stability drawn from a refractive index gradient spanning negative and positive values includes a two-dimensional array of tapered nanowells. A multilayer of alternating materials is associated with the two-dimensional array of tapered nanowells. The multilayer of alternating materials are alternating layers of electrical conductors and electrical insulators.
