Polarizability of asymmetric dielectric double sphere
This applet calculates the normalized (divided by volume and
permittivity of free space) polarizability of the dielectric
double-sphere having the relative permittivities of the two sides
e1 and e2, radii a and b, and distance
between centers of the spheres d. Note that the polarizability
is uniaxially anisotropic, and the polarizability components are
different in the axial (z) and transversal (t)
directions. The digits shown are correct.
