The complex dielectric function of a metal at low frequencies can be approximated as ε(ω) = ε' + iε'', where ε' is the real part and ε'' is the imaginary part. The reflection coefficient at normal incidence is given by R = (2ωε''/c) / (1 + (4πσωε'/c)), where σ is the static conductivity.

A flat linear dielectric surface, whose relative permittivity is 4, is subject to an electric field with an electric flux density of 6 C/m², and the dielectric is uniformly polarized. The electric field is perpendicular to the slab. The volume of the dielectric is 5 m³. What is the value of polarization?

Problem 5 : Two dielectric media permittivity’s ε₁ and ε₂ are separated by a charge-free boundary as shown in the Figure. The electric field intensity in medium 1 has a magnitude E₁ and makes an angle θ₁ with the normal. Determine the magnitude and direction of the electric field intensity in medium 2. This refraction of the electric field is equivalently described as the Snell’s law. Can the medium 1 be polyester and the medium 2 be mica? Explain your answer.
