Strunck, Sebastian and Karabey, Onur Hamza and Gaebler, Alexander and Jakoby, Rolf (2012):
Reconfigurable waveguide polariser based on liquid crystal for continuous tuning of linear polarisation.
In: Electronics Letters, 48 (8), pp. 441 -443, [Article]

Abstract

A reconfigurable waveguide polariser for changing the linear polarisation of the TE11 mode in a circular waveguide is presented. A liquid crystal based twisted nematic cell concept, similar to a liquid crystal display, is innovatively adapted for the tunable RF polariser. The polarisation state can be continuously turned in the range from 90° to -90° with a relatively low insertion loss between 4 to 5 dB at 50 GHz
