Parametric Excitation of Alfv6n Waves in the Ionosphere
نویسندگان
چکیده
A novel method for the excitation of ELF waves in the ionosphere is presented. It utilizes the nonlinear mixing of two groundor satellite-produced radio frequency waves with a compressional Alfv6n wave. Parametric amplification thresholds are estimated to be between 10 and 20 MW peak power for 5-MHz pumps producing waves in the ELF range. Potential applications to ELF communications are discussed.

متن کاملOn the Backscatter Instability of Solar Wind Alfvn Waves
A coherent Alfv6n wave propagating along the equilibrium magnetic field is unstable against decay into an Alfv6n wave traveling in the opposite direction and a sound wave [Sagdeer and Galeev, 1969]. The stability of incoherent Alfv6n waves against his mode decay is considered, assuming that the sound waves are damped. The criterion for stabilizing waves with power spectral density In o• k -N is...
متن کاملA New Mechanism for Interpreting the Motion of Auroral Arcs in the Nightside Ionosphere
A new mechanism is proposed for predicting and interpreting the motion of auroral arcs observed in the nightside ionosphere during the expansion phase of a substorm. This mechanism is centred on the idea that such arcs act as visible manifestations of the arrival of earthwardpropagating shock waves in the near-Earth magnetosphere. These shock waves are generated at a near-Earth X-line, and prop...
متن کاملELF Generation in the Lower Ionosphere via Collisional Parametric Decay
Generation of ELF waves by stimulated parametric coupling of two HF waves in the lower ionosphere is considered. In this region the nonlinear force is dominated by the thermal rather than the ponderomotive nonlinearity. It is shown that this results in lowering the pump threshold for complete decay by more than an order of magnitude while achieving efficiencies in excess of those expected on th...
متن کاملThe Response of Two-Degree of Freedom Self-Sustained Systems with Quadratic Nonlinearities to a Parametric Excitation (RESEARCH NOTE)
In this study the interaction between self-excited and paramet rically excited oscillations in two-degree-of-freedom systems with quadratic nonlinearities is investigated. The fundamental parametric resonance of the first mode and 3:1 internal resonance is considered, followed by 1:2 internal and parametric resonances of the second mode. The method of multiple time scales is applied to derive f...
