Description
Summary:In this paper a solution for the focalization of the new 40‐m radiotelescope at the observatory of the Centro Astronómico de Yebes (CAY) in Guadalajara, Spain, is presented. Quasi‐optics theory is used in this paper for the propagation analysis of the beams through the different optics elements. The goal of this paper is to design an optical system that can focalize several bands in order to reduce to the minimum number of possible optic elements, and share the maximum number of them. Parameters for hyperbolic lenses and ellipsoidal mirrors, focal distances, and the feeder dimensions necessary for the focalization in each band are calculated. © 2003 Wiley Periodicals, Inc.
