Abstract :
Method of dielectric investigation of liquid crystals (LQ) confined into porous silicon (PSi) is described. Individuality technique for dielectric measurements consists oa using two type sensors, switching as a system elements in the microstrip resonance contour. The effective permittivity and molecular alignments of PSi with LQ (8CB) is determined in frequency range 103 - 5 times 108 MHz.
