The dynamics of dielectric particles with Quincke rotation under nonuniform electric fields generated by ion traps are researched. Based on a recently proposed model, I make a further discussion about a quadrupole electric field with numerical simulation. According to the results, the steady state of a single particle under different field strength can be classified into several stages. Some more complicated electric fields are considered too. But the dynamics of particle under other multipole fields can’t be simulated well with the model, which indicates that the model still needs to be improved. A more complicated 3D electric fields are considered too, the evolution of steady states under this 3D electric field is similar to the quadrupole field.
