Dispersion (`plasmapy.dispersion`)

The dispersion subpackage contains functionality associated with plasma dispersion relations, including numerical solvers and analytical solutions. It provides tools to relate wave frequency and wavenumber in plasmas, analyze wave propagation, and study the growth and damping of instabilities under different conditions.

Attention

This feature is under development. Breaking changes may occur in the future.
