Consider the problem of determining the reflectance from an isotropic medium as shown above. For simplicity, we will assume that the dielectric tensor for the medium is diagonal and is given by:
| (1) |
| (2) |
| (3) |
|
| (5) |
| (6) |
| (7) |
| (8) |
| (9) |
Below we consider two different polarizations for the electric field.
| (10) |
|
| (12) |
| (13) |
| (14) |
| (15) |
|
| (17) |
This result reduces to Eq. 7.41 in Jackson for the isotropic case.
