Consider a plane wave incident from medium#1 having a refractive index n=1.33 to air (medium# 2). The angle of incidence is . The incident electric field is polarized along the y-direction. The wavelength of operation is = 600mm. #2 (air) #1(n=1.33) 0 1) What is the angle of incidence at which the reflection coefficient is exactly equal to R=1? [2 points] 2) Is there an angle of incidence for which the reflection coefficient vanishes? Explain. [2 points] 3) Consider the case for which the angle of incidence is = 30. Calculate the corresponding wave impedance for the tangential field components in medium #1 and in medium #2 (air). [4 points]
