Abstract
A new family of 2-D nonimaging concentrators is presented. The most significant characteristics of these concentrators are their small size and the fact that they use straight, as opposed to curved, reflective, or refractive interfaces. The concentrators are filled with a medium of refractive index n > 1 and use narrow strips of refractive index ns < n. These strips are transparent, or act as mirrors, depending on the angle of incidence of the rays. The direction of the collected rays (i.e., rays reaching the receiver) at they entry aperture can be varied by modifying the refractive indices of the strips.
