The electric-field-induced structures of small glass spheres in silicone oil produce laser diffraction patterns which verify, for the first time, the body-centered-tetragonal lattice structure predicted by theory. By a mechanism totally unlike that of conventional x-ray scattering, the incident laser beam propagates through the lattice of close-packed spheres via stable optic modes along regular arrays of transparent spheres, and then produces diffraction patterns after exiting from the lattice.
Chen et al. (Mon,) studied this question.
