On the left of the interface the electric field is given by
 |
(9) |
and on the right hand side of the interface the electric field is given by
 |
(10) |
Maxwel's equations give us the relationship between the electric and magnetic fields for a plane wave.
 |
(11) |
which simplifies to:
 |
(12) |
Applying equation 12 to equations 9-10, we can get the magnetic field on the left of the interface
 |
(13) |
and on the right of the interface
 |
(14) |
Tidying up gives,
