In this work, we theoretically and experimentally study the conversion from acircularly polarized plane electromagnetic wave into a linearly polarizedtransmitted one using anisotropic self-complementary metasurfaces. For thispurpose, a metasurface design operable at sub-terahertz frequencies is proposedand investigated in the range of 230-540 GHz. The metasurface is composed ofalternating complementary rectangular patches and apertures patterned in analuminum layer deposited on a thin polypropylene film. The term\textit{self-complementary} implies that the pattern is invariant with respectto its inversion (with some translation). Our study shows that thetranslational symmetry of the metasurface results in unusual and usefulelectromagnetic properties under illumination with circularly polarizedradiation beams. In particular, alongside with broadband circular-to-linearconversion, the transmitted wave exhibits a frequency independent magnitude,while its polarization angle gradually changes with frequency that paves theway for new beam-splitting applications.
