Abstract
In order to get maximum power transfer from a waveguide mode into the gaussian freespace mode it is necessary to transform a rectangular part of a cylindrical caustic into the caustic of a gaussian beam. The design of a quasi optical antenna is reduced to a caustic transformation problem which can be solved by at least two mirrors. The gaussian beamwidth and the direction of the beam can be choosen as a free parameter.
