Abstract

Utilizing flow line or geometric vector field analysis we have arrived at an alternative explanation of why nonimaging optics is capable of achieving solar concentration and effective illumination with close to 2nd law of thermodynamics limit. In this paper we will discuss the minimum setup or configuration of such a nonimaging optics problem and how flow line field provides a different perspective on how nonimaging optics work.
