This expert and self-contained authored handbook provides comprehensive coverage of liquid crystals from the fundamental materials science, physics, and modeling through cutting-edge applications. Written by an author with over 40 years of active experience in this growing field, it offers an unprecedented self-contained treatment of this key research area. Liquid Crystals are a state of matter sharing properties that are usually associated with both solids and liquids. Their study belongs to wider field of soft condensed matter physics, an area growing in importance because of the new physics being discovered and the possibilities of various technological applications being developed. Liquid crystals continue to have a revolutionary technological impact and consistently pose new challenges of basic understanding. While the experimental side of liquid crystal research is very well developed, theoretical understanding has lagged, and this volume fills a gap in thepublished literature in terms of rigorous treatment of mathematical and computer modeling approaches. Volume I of this handbook deals with the physical foundations and fundamental aspects of liquid crystals, addressing their physical properties, measurement techniques, and various types. Overall, this handbook serves as the ultimate scholarly guide for researchers, scientists, and engineers seeking to unlock the full potential of liquid crystals. It offers a comprehensive understanding of these materials and their diverse applications, empowering readers to navigate the complex intricacies of liquid crystal science and technology.

Liquid crystals (LCs) represent a soft state of matter exihibiting symmetry and properties in-between crystalline solid and isotropic liquid. Due to existence of large anisotropy coupled with the collective molecular reorientation, the impact of liquid crystalline materials on the modern day science, technology, industry, engineering, biology and medicine has been very profound. The interest and activities in this fascinating field are undergoing a modern day renaissance. Recently, work in the area of science and technology of LC materials have preceded mainly in two directions: to synthesize new LC materials with specific characteristics appropriate for applications and to make composite systems by the dispersion/doping of non-mesogenic materials (dyes/polymers/nanomaterials) into the host LC matrix and tailor their properties suitable for the applications. The work described in this monograph presents investigations on the dielectric and electro-optical properties of pure and non-mesogenic materials dispersed in host LC systems and study of their basic and applied aspects. Some of the future challenges and problems which are to be addressed and explored are also pointed out.
