Abstract

Known designs of reflectors for cylindrical absorbers with gaps either suffer from radiation losses or from dilution which is equivalent to losing maximum concentration. In order to avoid both kinds of losses the global shape of a micro-structured reflector must be such that the gap and the real absorber occupy equal projected angles as seen from all locations. This condition is used to tailor the global shape. We show ideal reflectors for different gap positions. There is no upper limit for the gap size imposed by physical laws.
