电磁波在任意磁偏角等离子体中的传播
Electromagnetic wave propagation in magnetized plasmas with arbitrary inclination angle
摘要
Abstract
In this paper,a current density convolution finite difference time domain method (JEC-FDTD) is extended to solve the electromagnetic wave propagation and resonance absorption in magnetized plasmas with arbitrary inclination angle.Firstly,we verified the correctness of the numerical algorithm,and analyzed the Faraday rotation as well as the wave propagation in magnetized plasmas of arbitrary inclination angle.Then,we obtained the characteristics of three types of plasma resonance absorption including plasma resonance,electron cyclotron resonance,and upper-hybrid resonance.The model is also applied to simulate the resonance during ionospheric heating experiments by high-power high frequency (HF) radio waves.Numerical results indicate the upper-hybrid resonance condition can contribute to the maximum absorption for ionospheric heating,which are important to explain the physical mechanism for nonlinear wave and particle interaction during ionospheric heating experiment.关键词
