TI  - Polarization-gratings approach to deformed-helix ferroelectric liquid crystals 
      with subwavelength pitch.

AB  - Electro-optical properties of deformed helix ferroelectric liquid crystal (DHFLC) 
      cells are studied by using a general theoretical approach to polarization 
      gratings in which the transmission and reflection matrices of diffraction orders 
      are explicitly related to the evolution operator of equations for the Floquet 
      harmonics. In the short-pitch approximation, a DHFLC cell is shown to be 
      optically equivalent to a uniformly anisotropic biaxial layer where one of the 
      optical axes is normal to the bounding surfaces. For in-plane anisotropy, 
      orientation of the optical axes and birefringence are both determined by the 
      voltage applied across the cell and represent the parameters that govern the 
      transmittance of normally incident light passing through crossed polarizers. We 
      calculate the transmittance as a function of the electric field and compare the 
      computed curves with the experimental data. The theoretical and experimental 
      results are found to be in good agreement.
