Figure: Incident wave k strikes plane interface between different media,<br />
giving rise to a reflected wave k ′′ and a refracted wave k ′ . The media<br />
below and above the plane z = 0 have permeabilities and dielectric<br />
constants µ, ɛ and µ’, ɛ’ respectively. The indices of refraction are<br />
n = √ µɛ and n ′ = √ µ ′ ɛ ′ .<br />
