(15 points) Write a Jones vector for each of the following waves, and describe completely (linear, circular or elliptical? what angle? right-handed or left-handed etc) the state the polarization of each. (a) E = iEn cos(kz - wt + -)- j2E cos(kz - cut + 4 b) E = iEn cos(ct - kz) + jE cos( ct - kz + ). (Note the order of ot and kz)
