Polarization Transformation in Twisted Anisotropic Media

Polarization transformation of plane waves propagating in twisted anisotropic media is studied theoretically and numerically. It is shown that rotation of linear polarization is effected by such a medium when the anisotropy is of the order of 2 to 1 and twist rates commensurate with the relative value of the dielectric constants of the medium are used (less than 15/spl deg///spl lambda//sub 0/ for low dielectric constants and up to 90/spl deg///spl lambda//sub 0/ for dielectrics in the vicinity of 1000).
