Figure 4.3: Coordinate system for linear reflectivity. A single reflection in the Ga~
film is displayed. The phase difference between the wave reflected from the surface
and the wave that is transmitted from the GaN film is 6.
fleeted electric field, E r , is expressed in terms of the incident electric field. E i , as

In equation (4.4), rij refers to the Fresnel reflection coefficient for p-polarized light
incident from medium i and reflected from medium j, tij is the Fresnel transmission
coefficient for p-polarized light incident from medium i and transmitted through
medium j, and 6 is the phase difference between the beams that are reflected from
the front and back surfaces of the medium 1 and can be expressed as
