Susceptibility anisotropy ellipsoids:
- a) sphere ($k_1=k_2=k_3$); radius in all three directions is the same
- b) oblate ellipsoid ($k_1 < k_2 ≈ k_3$); radius in one direction is shorter (“flat pill”)
- c) prolate ellipsoid ($k_1 > k_2 ≈ k_3$); radius in one direction is longer (“needle”)
- d) triaxial ellipsoid ($k_1 \neq k_2 \neq k_3$); the radius is different in all directions (e.g. similar to a “surfing board”)
