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 specified values of magnetic field and plasma density. Source code is available at github.com/CMA-Lab/CMA-Diagram.
