[Pw_forum] Real and imaginary part of dielectric function

I wish to calculate optical properties,
If i understood correctly 'epsi.dat' represents the absorption (imaginary),
while 'epsr.dat' the reflectivity (real part).
The output used to have 3 components like epsi_x, epsi_y, epsi_z
But in the literature everywhere imaginary and real have two components perpendicular and parallel.
What should i do to get these parallel and perpendicular from x,y and z components of output ????
Sorry for a very silly question.
