Book 1991ugh many significant results were found, liquid crystal research remained a marginal topic of condensed matter physics. The situation changed in the sixties. At that time the remarkable electro-optical properties of liquid crystals were recognized and found soon widespread application in numeric dis

Rotatory Power and Other Optical Properties of Certain Liquid Crystals second important parameter is the value of the double refraction . = (.. - ..)/.. From . and . all optical properties can be calculated. No accurate data for testing the theory are available but qualitatively the agreement is complete.

Study of Phase-Matched Normal and Umklapp Third-Harmonic- Generation Processes in Cholesteric Liquidron interaction in a periodic lattice, these processes can be identified as coherent, normal, and umklapp third-harmonic-generation processes. Experiments using a mode-locked Nd laser as the fundamental source verify the existence of most of the predicted phase-matching conditions. Our results agree well with the theoretical predictions.

Reflection and Transmission by Single-Domain Cholesteric Liquid Crystal Films: Theory and Verificatiany linear optical medium in which the dielectric tensor varies only in a direction normal to the surfaces. Using this technique with Oseen’s spiraling-dielectric-tensor model of a single domain in a cholesteric liquid crystal, we predicted triplet Bragg reflection bands of both first and higher ord

Light Propagation in Anisotropic Stratified Media in the Quasi Adiabatic Limitctor is continuously rotating through the sample with an arbitrary law. In this approach a simple, 2x2 Jones matrix is obtained by proper transformation of the conventional 4x4 Berreman matrix. An approximate propagation equation is deduced for the Jones vector giving the polarization state of the w
