A plane wave is propagating through a homogeneous free space, and is defined by: \mathbf{E}=\hat{\mathbf{A}}_{x} 1 e^{-j \beta z}-\hat{\mathbf{a}}, 1 e^{-j \beta z} e^{-j \frac{\pi}{2}} a) Determine the polarization of

the wave (linear, elliptical, circular) and the handedness of polarization. determine the power density of the wave and the direction of power flow
