polarized at right angles to the plane of incidence
and strike the bounding surface at the angle of polarization" [5, [section] 37].
For example in the x-z plane of incidence
, the reflection coefficient for the TM (Transverse Magnetic) or p-polarization is
Let the Cartesian coordinate system be chosen such that z axis coincides with the axis of spheroid, z be equal to 0 in its center, and the plane of incidence
coincides with the plane y = 0.
H], the component of beam w transverse magnetic polarized (TM)--its magnetic field is perpendicular to the plane of incidence
When the scratch is oriented horizontally, the reflections from the scratch contours are rotated off the plane of incidence
and are absent in the measurement at all angles (Fig.
Because SE measures the phase shift between light that is polarized parallel and perpendicular to the plane of incidence
, it can be used to measure retardance when the ellipsometer and sample are correctly oriented.
For reflection, the incident light wave is resolved into components in the plane of incidence
and normal to the plane of incidence
(the plane of the surface).
Here, parallel polarization means that vector E is parallel to the plane of incidence
When the linearly polarized light interacts with the optical surface, there is a shift in phases of both the components parallel and perpendicular to the plane of incidence
The electric vector of the incident light is parallel to the plane of incidence
for p-polarized light.
These quantities are related to the ratio of the Fresnel reflection coefficients for the light polarized parallel and perpendicular to the plane of incidence
However, mode PT, which is polarized perpendicularly to the plane of incidence
, cannot be excited by mode conversion.
