abstract = {<p style="text-align: justify;">A multiple-image method is proposed to approximate the reaction-field potential
of a source charge inside a finite length cylinder due to the electric polarization
of the surrounding membrane and bulk water. When applied to a hybrid ion-channel
model, this method allows a fast and accurate treatment of the electrostatic interactions
of protein with membrane and solvent. To treat the channel/membrane interface
boundary conditions of the electric potential, an optimization approach is used
to derive image charges by fitting the reaction-field potential expressed in terms of
cylindric harmonics. Meanwhile, additional image charges are introduced to satisfy
the boundary conditions at the planar membrane interfaces. In the end, we convert
the electrostatic interaction problem in a complex inhomogeneous system of ion channel/membrane/water
into one in a homogeneous free space embedded with discrete
charges (the source charge and image charges). The accuracy of this method is then
validated numerically in calculating the solvation self-energy of a point charge.</p>},
