Propagation of Polarized Light through the PDFLC Monolayer

On the basis of the amplitude-phase screen model an analytical expression for the coherent transmittance of the polymer-dispersed ferroelectric liquid crystal (PDFLC) monolayer normally illuminated by linearly polarized plane wave has been obtained Within the framework of the anomalous diffraction approach the conditions for coherent transmission quenching have been determined. It is shown that for the PDFLC monolayer on the basis of bistable smectic liquid crystals it is possible to provide a coherent transmittance equal to zero and unity for two stable states of droplet directors in electric field. The influence of polydispersity for the gamma-size distribution of droplets on the quenching conditions of coherent transmission has been investigated.
