These profiles show the steepening of the electron density oscillations and the non-sinusoidal shape of the magnetic field.
Visible harmonic emission as a way of measuring profile steepening.
There are again several branches of solution, including the curly waves and the steepening sharp waves.
The implied steepening of the density profile indicates that the reduction of neutral pressure is accompanied by a change in the source profile.
Extended nonlinear calculations exhibit recurrence, in some cases, and attrition of the vortex by repeated wave amplification, steepening, and breaking in others.
Although this is a highly speculative picture of the post steepening phase, something like this appears to occur in our laboratory experiment (figure 1).
Thus, the trapping effects due to the density gap and the density steepening become weak.
This work is converted into short-wave energy, and produces a steepening of the short waves beyond what was previously expected.
