  • Abstract
    Tunable polarisation transformers for axially corrugated waveguides are proposed. The polarisation transformer consists of a uniaxially anisotropic waveguide section and a ferrite filled waveguide section. The polarisation of the field is changed when propagating through the anisotropic waveguide section. The state of the polarisation depends on the ratio of the axial field components which can be changed by external magnetic field in ferrite filled waveguide section.
