Summary:The electrostatic characteristics of the spherical dust particle on the PFM were investigated analytically by introducing the bipolar coordinate in the plasma sheath field. The smaller dust compared to the Debye length λD is applicable to this model. It is clarified that the effect of finite size of the dust becomes remarkable at the larger dust than 0.2, Rd/λD > 0.2, where the change of the e‐folding length amounts to 10% of λD. The surface charge density on the dust is disturbed on the surface facing to the plasma due to the larger dust. (© 2016 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
