FIELD: physics.
SUBSTANCE: terahertz radiation modulator consists of a stack of liquid crystal cells, each of which is composed of two substrates separated by spacers. The inner sides of the substrates are processed to give a LC homogeneous orientation along the surface of the substrates. Each of the LC cells of the stack is provided with two sections of a porous membrane located between the substrates and along the edges of the cell. The sections of the porous membrane are separated from the substrates by spacers, forming cavities filled with LC.
EFFECT: providing modulation of terahertz radiation with low voltages inherent in LC, and short switching times.
