Abstract
In this paper is presented a solution for the focalisation of the new 40 m radiotelescope of the Centro Astronomico de Yebes (CAY) in Guadalajara, Spain. 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 the optical system that can focalize several bands reducing to the minimum number of possible optic elements, and sharing the maximum number of them. Hyperbolic lenses and ellipsoidal mirrors parameters, focal distances, and the feeder dimensions necessary for the focalization in each band are calculated.
