Question: Question 3 Consider an interface between air ( = 1) and a dielectric medium with = 4. An incident plane wave of the phasor

Question 3 Consider an interface between air ( = 1) and a dielectric medium with = 4. An incident plane wave of the phasor form: - (+258 +18- 1 --/22 ) e is impinging upon the dielectric (occupying the space > 0) from air as shown in the figure below. (x) Air & = 1 0 -j2T = (1+1/2 + z=0 1 +/-) Dielectric E 9 (z) 1. What is the angle of incidence, and the wavelength of the incident plane wave? 2. Determine the reflected electric field (in z < 0), in phasor form. 3. Determine the transmitted electric field (in z > 0), in phasor form. 4. Determine the polarization of the incident wave. 5. Can you choose the angle of incidence, to ensure that the reflected wave is linearly polarized? If yes, what is the angle? If not, why not?
