Nonstandard refraction of light from one-dimensional dielectric quasi- periodic surfaces

摘要

Not only do meta-materials have the properties of negative refraction, the planar designer surfaces have shown some of these properties as well.rnRecently, we have undertaken an experimental study of nonstandard refraction of light from one-dimensional dielectric quasi-periodic surfaces. The mechanism behind this is the large local slope of the quasi-periodic surface that causes the nonstandard refraction.
