Design of a Scheffler Mosaic Mirror by Optical Raytracing and CAD Software
SolarPACES Conference Proceedings, 2023 The Scheffler reflector is a parabolic metal concentrator, typically applied in solar thermal systems with receiver fixed to the ground. The Scheffler mirror is deformed during the year to optimize its solar light collection. For practical reasons it is

Casimir force between metallic mirrors [PDF]
The European Physical Journal D - Atomic, Molecular and Optical Physics, 2000 We study the influence of finite conductivity of metals on the Casimir effect. We put the emphasis on explicit theoretical evaluations which can help comparing experimental results with theory. The reduction of the Casimir force is evaluated for plane metallic plates. The reduction of the Casimir energy in the same configuration is also calculated.
