What does $e$, $i$ and $\vec{p}$ mean in this formula? [closed]
I've found a formula to calculate the $\vec{E}$-field vector of a Hertzian dipole in the far field (don't know if that's the correct term) to draw and simulate the field lines.
Link to my source: ...

Spherical wavefronts from a linear electric dipole-antenna
We are given the equation
\begin{equation*}
\vec{E}=\hat{u}_\theta\ p_0 \sin{(\theta)}\frac{k^2}{4\pi\varepsilon_0r}\sin{(kr-\omega t)}~,
\end{equation*}
that describes the far field radiated ...

Why does a ionic crystal polarize more at low frequencies rather than at high ones?
And if there was a difference if the propagational mode of the electric field in the crystal is longitudinal or transverse.
