Abstract

The nematic liquid crystals in devices with non-linear characteristics, studies were carried out for their electrophysical properties under stationary and microwave electric and magnetic fields. An essential point of our study is the use of two substantially different types of LC (with Deltaepsiv values of opposite signs) in parallel sets of experiments. This allowed us to account, at a qualitative level, for effects of LC orientation and texture upon bulk electric properties.
