Abstract
Variable liquid crystal devices for controlling the propagation of light through a liquid crystal layer use a frequency dependent material to dynamically reconfigure effective electrode structures in the device. The drive signal source uses pulse-width modulation to set a frequency and an amplitude of the drive signal.
