\section{Appendix}  For Appletons's equation, the electron cyclotron frequency is given by \[\omega_{ce}=\frac{eB}{m_e}\] where $e$ is the elementary charge, $B$ is the magnetic field and $m_e$ is the electron masst The masst.The  plasma frequency is given by \[\omega_{pe}=\sqrt{\frac{ne^2}{m_{e}\epsilon_0}}\] where $n$ is the plasma density,and $\epsilon_0$ is the permittivity of free space and $\nu$ is the collision frequency.
