Abstract

By using existing metal mesh technology we propose a new lens design that behaves in a similar way to a Wollaston Prism. That is, a device that separates out the two linear polarised states of the incident field and then focuses them separately on same focal plane. The design is an evolution of an existing GRIN lens based on the same technology. The proposed lens design has a diameter of 75mm while only being 2mm thick. This will focus two beams at a distance of 250mm with a separation of 10mm, over the frequency range of 100-200GHZ. Such a device would be useful where space and weight are an issue and would allow the use of incoherent detectors.
