Posing the problem
What happens when light, propagating in a
uniform medium, encounters a smooth interface
which is the boundary of another medium (with a
different refractive index)?
k-vector of the
incident light
nincident boundary First we need to
ntransmitted
define some
terminology.
Definitions: Plane of Incidence and
plane of the interface
Plane of incidence (in this
illustration, the yz plane) is the y
plane that contains the incident
and reflected k-vectors. z x
Plane of the interface (y=0, the xz plane) is the plane that
defines the interface between the two materials
