Interaction of acoustic signals was investigated in a cell of ferroelectric liquid crystal (FLC). Oscillation lines of both the initial and the combination frequencies were detected in the spectrum of the electromechanical response. Dependencies of the vibration parameters of combination frequencies on the vibrations parameters of the sound and ultrasonic excitation were investigated. Combination frequencies appear as a result of non-linear dynamical properties of FLC.

Abstract— Photoinduced changes that were revealed for ferroelectric liquid‐crystalline systems with helical supra‐molecular structures induced with chiral α,β‐unsaturated ketones have been summarized. Photoinduced inversion of the spontaneous polarization sign and a concomitant increase in its absolute value and other ferroelectric parameters were observed. The E‐Z photoisomerization of the chiral compounds was determined to be responsible for the discovered effects.
