Dispersion diagram


  1. Full wavelength.

  2. Quarter wavelength, seen from perspective.

  3. Quarter wavelength and vector field.

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

  5. Quarter wavelength, seen from the z-direction including the velocity field.


  • 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)
