Frequency dependence of arrival direction and polarization of low‐latitude whistlers and their ducted propagation

The combined use of digital recorders and a fast Fourier transform analyzer made it possible for them to carry out wideband field analysis direction finding measurements of whistlers at low latitude (geomagnetic latitude 25{degree}N). It is found that there is a negligibly small frequency dependence of the ionospheric exit point and polarization of daytime whistlers during each occurrence peak with duration of about 2 hours, which lends further support to their propagation in a field-aligned duct in the magnetosphere for each occurrence peak.
