均匀磁化等离子体中偶极子辐射的推导
Derivation of Radiation from a Dipole immersed in a Homogenous Magnetized Plasma
摘要:
我们考虑一个偶极天线浸在冷等离子体和研究其辐射模式。我们使用(1)天线平行于磁场$B_0$的情况下的解析解和(2)天线的任何方向和角度$θ$的数值解来求解麦克斯韦方程。我们研究了不同的相速度制度,以及不同的频率和等离子体参数对电磁波的影响。
英文摘要:
We are considering a dipole antenna immersed in cold plasma and investigate its radiation patterns. We are solving Maxwell's equations using (1) analytic solutions for the case when the antenna is parallel to the magnetic field $B_0$ and (2) numerical solutions for any orientation and angle $θ$ of the antenna. We investigate various phase velocities regimes as well as the effect of varying the frequency and the plasma parameters on the electromagnetic waves are presented and discussed.
