Fig. 15. Polarization coefficients for the mean square voltages detected by a pair of
orthogonal linearly polarized antennas placed at Jicamarca. The antennas have very narrow
beams and scan the ionosphere from north to south probing different magnetic aspect angle
directions. Note that, for most pointing directions, the polarization of the detected fields
rotates (Faraday rotation effect), except in the direction where the beam is pointed
perpendicular to
B
, in which case, the type of polarization changes from linear to circular
(Cotton-Mouton effect).
