A uniform plane wave is traveling in the positive z-direction. Determine the polarization (linear, circular, or elliptical) for each Amplitude and Phase information of two orthogonal components. In all cases, justify the answer. (Hint: Conditions of Achieving Different Polarization) I. Ex = Ey, φy − φx = 0 II. Ex ≠ Ey, φy − φx = 0 III. Ex = Ey, φy − φx= π/2 IV. Ex = 0.5Ey, φy − φx = π/2
