The 0º-polarization angle is related to x-polarized incidence (a). The 45º-polarization angle is related to the incidence polarized 45º with respect to the x axis (b). The 90°-polarization angle is related to y-polarized incidence (c). The 135°-polarization angle is related to the incidence polarized 135º with respect to the x axis (d)
