title: Ray tracing through funnel concentrator optics.
abstract: A procedure and equations are presented for tracing meridional and skew rays through some funnel concentrators proposed as solar energy collectors. These concentrators are general toroids generated from parabolic or elliptical surfaces. The ray tracing procedure uses an iterative technique with exact tracing to conical surfaces tangent to the concentrator.
