Dynamic equation for the polarization state in inhomogeneous anisotropic media.
A dynamic equation for the polarization state is derived to analyze the transmission of light in inhomogeneous anisotropic media including liquid crystals. This method is an extension of the Jones matrix method, with a higher accuracy, and is valid for arbitrary incident angles. As an example, the dynamic equation is employed to analyze the evolution of the polarization state of a beam of light in a twisted nematic liquid crystal. The results are presented and discussed.
