Abstract
A simple model is proposed to describe the electrooptic response of po lymer dispersed liquid crystals. A hierarchy of order parameters is in troduced to describe orientational order on different length scales. E xternal fields reorient the liquid crystal in the inclusions, and thus alter the orientational order. The resulting changes in the dielectri c and optical properties of the sample are taken into account via chan ges in the order parameters. The transmittance of PDLC films is consid ered as a function of static and time dependent magnetic and electric fields.
