Now in the special case when the rays are polarized at right angles to the plane of incidence and strike the bounding surface at the angle of polarization, p = 0, and p' = 0.
For consideration of the reflection process on the Poincare sphere, represent the light with respect to Cartesian coordinates with the X and Y axes in and normal to the plane of incidence and the Z axis in the direction of propagation.
By eq (6) this corresponds to zero ellipticity, [chi], and azimuth [varphi] so it represents the orientation of the X axis, or the plane of incidence.

The geometry of this half space case in the plane of incidence (defined by [phi]) with angle of incidence [theta], is shown in Figure 3.
In this first half-space problem case, we consider the plane of incidence to be the y-z plane ([phi] = 90[degrees]).

Since a disk has rotational symmetry with respect to z-axis, we can assume without loss of generality that the plane of incidence lies in xz-plane ([[phi].
The incident vector and the normal vector at the intersection point on the inner surface define the plane of incidence.
