RT Journal Article T1 Ideal 3D asymmetric concentrator A1 García Botella, Ángel A1 Álvarez Fernández-Balbuena, Antonio A1 Vázquez Moliní, Daniel A1 Bernabeu Martínez, Eusebio AB 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. PB Pergamon-Elsevier Science, Ltd.
