The spatial variations of the electric field of a time-harmonic wave traveling in free space are given by

Determine the:

(a) Direction of wave travel (+x, -x, +y, -y, +z or -z) based on e^+j?t time.

(b) Two pairs of Poincare sphere polarization parameters (?, d) and (e, t ).

(c) Based on either one of the two pairs of parameters from part (b), state the:

• Polarization of the wave (linear, circular or elliptical). Justify your answer.

• Sense of rotation (CW or CCW) of the wave. Justify your answer.

• Axial Ratio. Justify your answer.
