Short Description

Displays the CMA diagram[1] of cold plasma radiofrequency phase velocity surfaces at point-and-click locations in the 2D space of magnetic field versus plasma density. This aids in visualization of plasma waves propagating in spatial varying plasma for for a sequence of specified values of magnetic field and plasma density. Source code is available at github.com/CMA-Lab/CMA-Diagram.
