Abstract
In microwave radio‐frequency technology, the design of broadband circular polarisers involves the use of waveguides having different propagation velocities for two orthogonal, linearly‐polarised modes. To achieve this aim, square ridged waveguides with dielectric inserts may be employed to disturb the symmetry of the dual linear polarisations. The computation of the cut‐off frequencies of the structure is achieved by the use of a finite‐element method which makes full use of powerful pre‐ and post‐processing techniques.
