Polarization gratings in the short-pitch approximation: electro-optics of deformed helix ferroelectric liquid crystals
Alexei D. Kiselev, Eugene P. Pozhidaev, Vladimir G. Chigrinov +1
Electro-optical properties of deformed helix ferroelectric liquid crystal (DHFLC) cells are studied by using a general theoretical approach to polarization gratings in which the tr…
