A plane wave of free space wavelength 1.5 μ m is incident on a dielectric interface as shown below. Since medium 1 has a higher index of refraction than medium 2, it is possible to have total internal reflection at this interface. x z i k G i H G i E G 80 o in θ = 10 1.69 εε = 20 1.44 = μμ = = (a) What is the critical angle? Is total internal reflection possible for the angle of incidence shown in the figure? (b) What is the polarization of the incident plane wave?
