Ray tracing analysis of L mode pumping of the ionosphere, with implications for the magnetic zenith effect

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...
