Whistler Wave Generation by Continuous High Frequency Heating of the Upper Ionosphere
We present the very first clear experimental observations of whistler waves generated by continuous heating of the upper ionosphere using the HAARP facility. The proposed generation mechanism relies on parametrically excited Lower-Hybrid (LH) waves and their linear and non-linear mode-conversion to whistler waves. After generalizing an existing LH-whistler conversion model, simulation results are presented that are in good agreement with the observed whistler wave spectrum. A combination of qualitative discussions and simulation results explains certain peculiarities observed in the spectrum.
