Abstract
We describe two families of Interactive Data Language (IDL) codes to calculate and display the dispersion relation for low frequency waves in Jupiter's polar cap. One set of codes solves the cold plasma dispersion relation, while the other set solves the fully kinetic dispersion relation.
Description
IDL files containing the software used to calculate the dispersion relation in both the cold plasma limit and the fully kinetic limit for waves in the regime below the electron plasma frequency and the ion cyclotron frequency. In Jupiter's polar cap, we encounter the unusual case that the electron plasma frequency is less than the ion cycltron frequency. This situation leads to a new type of plasma wave mode that acts like an Alfven wave at long wavelength and a Langmuir wave at shorter wavelengths.
