 \section{(4,5 points)}
 A ground station is emitting a plane wave toward a satellite, with an elevation angle $\alpha_1=10^o$. The electric field is horizontally polarized. The atmosphere is modelled as two dielectric layers separated by a horizontal interface. The relative dielectric permittivity of the two layers is $\epsilon_1$ and $\epsilon_2 = 1.01\epsilon_1$ respectively.
