Interaction between light and matter in an absorbing medium

2 Interaction between light and matter in an absorbing medium 

In an absorbing medium, fhe refractive index n and fhe magnefic perme-abilify p are formally replaced by fhe complex refractive index h and fhe complex magnefic permeability jl, respectively, 

In fhe cormecfion befween Eq and Hq, hip can be replaced by n since fhe complex refractive index can be sef equal fo n and fhe complex magnefic permeabilify p can be sef equal fo 1. 

The previous expressions for the wave vectors for linearly and circularly polarized light have to be modified as follows.
