Key Equations

$$\frac{n_i n_e}{n_n} = 2.4 \times 10^{21} \frac{T^{3/2}}{g_i/g_n} e^{-E_i/k_B T} \quad \text{[m}^{-3}\text{]}$$
$$r \gg r_c = \frac{e^2}{4\pi\epsilon_0 k_B T}$$
$$\mathbf{J} = -n_e e \mathbf{v}_e = \frac{n_e e^2}{i\omega m_e}\mathbf{E} = \sigma(\omega)\mathbf{E}, \quad \sigma(\omega) = \frac{i n_e e^2}{\omega m_e}$$
$$\frac{e^2 n_e L^2}{\epsilon_0 k_B T} \gg 1 \quad \Rightarrow \quad L \gg \lambda_D$$

Equations are rendered with MathJax in the PDF with professional LaTeX typesetting.
