For
simplification, we consider a linearly polarized plane wave which propagates
along the
positive z direction and vibrates in the x-plane. The electric field of the
wave can
be written as:
where Ex is the x-component of the electric-field strength; e is the dielectric
constant; s is
the conductivity.
w (=2pn) is the angular frequency, E0 is the maximal
value of the electric field strength.
is the complex index of
refraction
