Polarizability calculator

This Java applet computes the elements of the polarizability tensor α for a general magnetic ellipsoid embedded in an isotropic medium:



ε1 and ε2 are the dielectric tensors of the material and embedding medium, respectively, k is the wavevector of the impinging light, and V is the volume of the ellipsoid. L and D are the static and dynamic depolarization tensors, respectively; the former accounts for the shape of the particle, the latter for the size. The elements of these two tensors are also calculated by the applet.
