Dispersion diagram


  1. Full wavelength.

  2. Full wavelength and the magnitude of the magnetic field perturbation in the xy-plane.

  3. Quarter wavelength seen from perspective.

  4. Quarter wavelength, seen from the z-direction.

  5. Quarter wavelength, seen from perspective including the velocity field.

  6. Quarter wavelength seen from the z-direction including the vector field.

  7. Full wavelength vertical slice.


  • x-axis (red arrow), y-axis (green arrow) and z-axis (blue arrow)

  • Red lines – magnetic field lines

  • Grey surface – slab boundaries

  • White arrows – velocity direction field

  • Density perturbation - red (high), blue (low)
