Using an antenna to generate whistler waves in a plasma using helium a source gas and a magnetic field probe to measure perturbations in the magnetic field, a biased disc was placed in front behind  of the wave generator to create ducting. A simulation Ducted waves were seen to propagate towards density minimum when in a region of high magnetic field, and then along a density maximum when alation  was also created using exact theory to compare with measured results.
