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:

(d) (9%) Assume the direction of the H field does not change upon retlection and transmission at the interface and the magnetic field amplitudes of the reflected and transmitted waves are denoted by and, respectively. Obtain the relation that the tangential components of the electric fields in media 1 and 2 must satisfy at x=  0.
