Q9 A plane wave traveling in a medium with a = 4 is normally incident upon a second medium with e2=9. Both media are made of non-magnetic, non-conducting materials. The magnetic field of the incident plane wave is given by H; = £10cos(2 x 6 x 10°t -ky) (A/m). (a) Calculate the wave velocity and wave number in medium 1; (4 marks) (b) Calculate the intrinsic impedances of medium 1 and medium 2; (4 marks) (c) Calculate the reflection coefficient and transmission coefficient; (4 marks) (d) Obtain instantaneous expressions for the incident and reflected electric fields in medium 1; (8 marks)
