Abstract
We present Monte Carlo computer simulations of model nematic droplets that mimic polymer dispersed liquid crystals (PDLC's) with bipolar bou ndary conditions. We investigate the orientational order and the molec ular organization in these systems for various anchoring strengths and for external applied fields of different magnitude both for positive and negative susceptivity anisotropy. We report a number of simulation s for system sizes from 304 to 11 752 particles and calculate powder d euterium NMR spectra and polarizing microscope textures for the variou s cases.
