Refractive Index Permittivity Relationship - Web using the expressions for c and cm, the refractive index of the material can be expressed in terms of ε and μ. Web thus, the relative refractive index is given by the relation n r = (μ r ∈ r ) 1/2 where the n r is the refractive index. N = ( μ 0 ε. Web to put it more accurately, the refractive index n~ is a complex function that depends among other things on the.
