Dielectrophoresis of non-spherical particles

Dielectrophoresis of non-spherical particles is attracting attention, particularly for the aligned deposition of nanowires and nanotubes. The orientation and translation of ellipsoids are studied theoretically, and it is found that the orientation plays a significant role in determining the particle trajectory. A new equation for dielectrophoresis is presented which allows for orientation to be taken into account. Numerical simulation of particle motion is performed to demonstrate these effects.
