Physics · Electromagnetic Theory
A plane electromagnetic wave from within a dielectric medium (with ε = 4ε0 and μ = μ0) is incident on its boundary with air at z = 0. The magnetic field in the medium is given by Ĥ = ĵ H0 cos(ωt - k√3x - kz), where ω and k are positive constants. The angle of refraction into the air is:
