Q4/ The complex magnetic field of a uniform plane wave is given by 10^-3 H = (ax + haz)e + jBy 120n a) Find the polarization of the wave (linear, circular, or elliptical). b) State the direction of rotation (clockwise or counterclockwise) and why? c) Sketch the polarization curve denoting the H-field amplitude and direction of rotation. Indicate on the curve the various times for the rotation of the vector.

Write down the (real) electric and magnetic fields for a monochromatic plane wave of amplitude $E_{0},$ frequency $\omega,$ and phase angle zero that is (a) traveling in the negative $x$ direction and polarized in the $z$ direction; (b) traveling in the direction from the origin to the point $(1,1,1),$ with polarization parallel to the $x z$ plane. In each case, sketch the wave, and give the explicit Cartesian components of $\mathbf{k}$ and $\hat{\mathbf{n}}$.
