摘要：

Particle-in-cell (PIC) simulations of electromagnetic (EM) pump wave propagation into an overdense, strongly magnetized plasma with a linear density gradient are investigated. A localized three-wave interaction is observed involving the pump decaying into upper and lower hybrid waves. The upper hybrid (UH) wave converts on pump induced density depletions into an electromagnetic wave which exits the plasma. When the pump wave frequency equals an electron cyclotron harmonic plus lower hybrid (LH) frequency, all excited waves vanish, implying a magnetic field strength remote diagnostic capability. These results are relevant to stimulated electromagnetic emissions (SEE) and also to electron heating in a strongly magnetized plasma.
