title: Anisotropy of electrostatic interaction in smectic-C^{*} liquid crystals.
abstract: The contribution to the free energy of distortion of the ferroelectric smectic-C^{*} due to the electrostatic interaction of polarization charges is calculated. These calculations are performed by accounting for the anisotropy of the permittivity, which is essential for smectic-C^{*}. Fluctuations of the c director in an external electric field are considered. It is shown that the anisotropy of the permittivity strongly affects the interaction of the polarization charges, the spectrum orientation fluctuations, and the angular dependence of the light scattering intensity.
