T1 CONVERSION OF ELECTROMAGNETIC WAVE POLARIZATION BY A REFLECTION GRATING OF SHORT-CIRCUITED COAXIAL SECTOR WAVEGUIDES JF Radio Physics and Radio Astronomy JO RPRA YR 2011 FD 2011-07-07 VO 2 IS 3 SP 265 OP 270 K1 reflecting grating K1 coaxial sector waveguide K1 polarization conversion K1 Stokes parameters AB Polarization properties of a reflective two-dimensionally periodic grating of short-circuited coaxial sector waveguides are analyzed. Frequency dependences of the Stokes parameters of the reflected wave are presented for the cases of normal and oblique incidence of a plane linearly polarized electromagnetic wave upon the grating. The Stokes parameters are analyzed in dependence on the length of the short-circuited coaxial sector waveguides. It is shown that a plane linearly polarized wave incident normally or obliquely upon the grating can be transformed into a reflected circular polarized wave with either clockwise or anticlockwise rotation of the electric field vector.
