 note = {P(論文), Highlights of recent Stanford University VLF research in the Antarctic include new observations of wave-induced particle precipitation and controlled experiments on nonlinear wave growth phenomena. Higher-than-expected levels of burst precipitation have been discovered inside the plasmasphere, near L=2,using subionospheric signal perturbations called "Trimpi events". Studies of burst precipitation have been extended to the region poleward of the plasmapause using the Siple transmitter signal as a waveguide probe. Experiments on the "coherent wave instability", using the amplitude and frequency modulation capability of the new Siple transmitter, have produced exciting new results. Examples are : 1) better definition of the power threshold for the stimulation of temporal wave growth, 2) generation of strong sidebands by unamplified "beat" waves and 3) generation of chorus-like elements within a band of simulated hiss. Using a new digital processing technique developed at Stanford, new features of the phase behavior of growing waves have been found. Opportunities for extending these experiments are discussed.},
