Programmed assembly of metallodielectric patchy particles in external AC electric fields

We present unusual microstructures formed by patchy metallodielectric particles under high frequency alternating current (AC) electric fields. These particles assemble into two-directional percolated networks and lattices of unusual symmetry by interactions pre-programmed by their patch size and orientation. Electrostatic simulation results indicate that the assembly pattern of the patchy particles is guided by quadrupolar and multipolar interactions.
