(a) Changes in orientation angle as κ is increased from 0 to 0.4 calculated at the frequencies where dominant power is reflected as cross-polarized fields. (b) The contour path traversed by locus tip of electric field vector in time at fixed frequency of 1.7 THz for $\kappa =0$ and $\kappa =0.4$. Inset provides the schematic illustration of orientation angle (τ) for the polarization ellipse.
