5. (27%) A uniform plane wave in a nonmagnetic simple medium 1 is incident upon a nonmagnetic simple medium 2 of half-space as shown in Fig. 1, where denote the free-space permeability and the absolute permittivity, respectively. According to the experimental data there is no reflection at some incident angle. Assume a time dependence of, answer the following questions:

(c) (5%) If the incident magnetic field of constant amplitude points in the y-direction, determine the phasor form of the incident electric field E_i.
