Abstract
We explain by a simplified theory the existence of the undulation instability found by us in thick samples of planar oriented S*c liquid crystals. We derive the order of magnitude of the threshold field and explain the minimum in the frequency dependence of the unwinding critical field Ec as well.Keywords
