A waveguide device comprises a first circular waveguide segment (CWS) that imparts a 3λ/8 relative phase shift to two orthogonal linearly polarized signals, and a second CWS that imparts a λ/8 relative phase shift to two orthogonal linearly polarized signals. A waveguide assembly (WGA) comprises the first CWS disposed coaxially adjacent to the second CWS. A source may provide dual linear polarized energy into the WGA. In a first mode, the first CWS is axially orientated relative to the second CWS, such that the first CWS polarization is offset by 90° degrees with respect to the second CWS polarization. The radiation source polarization may be offset by 45° relative to the first CWS polarization and the second CWS polarization. In a second mode, the first CWS may be orientated with respect to the second CWS, such that the first CWS polarization and the second CWS polarization are substantially the same.
