Abstract

We investigate, both analytically and numerically, a simple model of the field induced double hysteresis loop in AFLC materials. This bilayer model of the bulk of an AFLC describes the free energy in terms of polar and non-polar interactions due to surface alignment, the electric field/dipole interaction in each layer and the dipole/dipole interaction between the layers. The static hysteresis loop is found analytically and the stability of each analytic solution is investigated. The dynamic switching characteristics are found numerically and then investigated as the system parameters and electric field characteristics are changed.
