| Zusammenfassung |
| Using ray tracing of ordinary mode HF waves in an ionosphere with
kilometre-scale field aligned density depletions, or ducts, we find that
transmission across the plasma resonance becomes possible at new locations as
rays are guided into the so-called L mode. Stronger transmitted fields are
seen in some directions, notably at inclinations close to the vertical or the
magnetic zenith (MZ). It is argued that the results could have implications
for the magnetic zenith effect, i.e., the increased plasma response that has
been observed around the MZ. |
