text: It can be seen from these equations, and also in the animation, that the fields at these distances are exactly in phase.
text: In this region, the fields are predominately reactive fields, which means the E- and H- fields are out of phase by 90 degrees to each other (recall that for propagating or radiating fields, the fields are orthogonal (perpendicular) but are in phase).
