Abstract
Quasi-optical polarisers can be used to create circularly polarised beams from linearly polarised ¯elds. These devices can be designed using planar metallic grids with sub- wavelength structures that behave di®erently along two orthogonal axes. On the one hand, their design is usually based on transmission-line codes that implicitly assume plane waves and normal incidence conditions. On the other hand, in real practical situations, these devices are used with Gaussian beams. In this work, we experimentally study the e®ects of a dielectrically embedded polariser made with photolithographic techniques on the Gaussian beam of a horn. The impact of the polariser on the beam is measured using a W-band (75{110 GHz) Vector Network Analyser.
