as
I(z)= Ie^(-2niwz/c)
where I = initial intensity
and ni=complex paert of refractive index
Homework Equations
I have tried the solving the solution using poynting vector.
I have been pondering over the question over the last two days without any success. I think i am making it more complicated than it needs. to be. I would appreciate it if you point me in the right direction .
