Maxwell stress tensor calculation offorces in AC dielectrophoresfs

摘要

In the conventional DC electrokinetics, electrophoresis re used to separate different particles according to their different mobilities or distribution coefficients. DC electrokinetics need special bigh voltage supply devices, which are not easy to be integrated with other micro-devices, and high voltage may also cause significant temperature increase in the electrolyte solution. High voltage gradients in solution are sources. Of computational errars in computation of forces acting on dielectric particles. In this publication effective dipole moment for two-dimensionai particles is developed and at the end some practical example is given.
