metadata.name: dc.description.abstract
metadata.value: We propose a theoretical approach and a numerical method for determining the Frank
  elastic constants based on the experimental dependence of the effective values of the permittivity
  components on the magnetic field. The theoretical task was to find the minimum of the free energy
  and then to solve the inverse problem on finding elastic constants by the least squares root minimizing
  with experimental data. The proposed approach combines strong and weak models with various
  pretilt conditions at the boundaries. This model also describes the inhomogeneity of the electric field
  inside the sample. The proposed method allows to achieve higher accuracy using a small amount of
  experimental data. This statement is confirmed by the error estimation study, which is also presented
  in this research. As an experimental sample, we used the gadolinium-based liquid crystal complex,
  since there are no data on the Frank elastic constants for this complex.
