3. Consider a square waveguide of side 2L, centered at the origin, with axis running parallel to the z-axis. The square cross-section is parallel to the xy-plane, so the 4 sidewalls lie at x = ±L and y = ±L. Consider the TE mode given by Eo x s in cos (kz - wt) = Eo-y sin (-) cos (kz-wt)- sin (kz -wt = (a) Find the time average of the Poynting vector, i.e. the average energy flux per unit...
