A slanted S-shaped nano-columnar (SSNC) thin film sculptured by oblique angle deposition is applied as an enhanced polarization converter. A growth model of a SSNC film is developed using available empirical equations for columnar thin films. The optimum sculpture parameters for a SSNC film to have high efficient polarization conversion are theoretically estimated and applied in fabrication. The designated SSNC films are sculptured and demonstrated to have high polarization conversion reflectance over a broadband and wide-angle range.
