You have two waves of the same frequency and polarization but propagating at and angle to each other E, cos(k, r-t) and E, cos(k, r-t). What is the Poynting vector direction and magnitude? Consider first the general case, then specifically the case of equal amplitudes and arbitrary angle between wavevectors k, and k₁, and finally the case of equal amplitudes and opposite directions.
