00925njm 22002777a 4500 dc García Botella, Ángel author Álvarez Fernández-Balbuena, Antonio author Vázquez Moliní, Daniel author Bernabeu Martínez, Eusebio author 2009 Nonimaging optics is a field devoted to the design of optical components for applications such as solar concentration or illumination. In this field, many different techniques have been used for producing reflective and refractive optical devices, including reverse engineering techniques. In this paper we apply photometric field theory and elliptic ray bundles method to study 3D asymmetric – without rotational or translational symmetry – concentrators, which can be useful components for nontracking solar applications. We study the one-sheet hyperbolic concentrator and we demonstrate its behaviour as ideal 3D asymmetric concentrator. 0038-092X 10.1016/j.solener.2008.07.004 https://hdl.handle.net/20.500.14352/51118 http://dx.doi.org/10.1016/j.solener.2008.07.004 http://www.sciencedirect.com Ideal 3D asymmetric concentrator
