Polarized Light in Liquid Crystals and Polymers deals with linear optics of birefringent materials such as liquid crystals and polymers. It gives a survey of light propagation in such media with special attention to applications. A unique feature of the book is its description of light propagation in micro- and nano-structured birefringent optical elements, such as lenses and gratings composed of birefringent materials. Spatial varying anisotropic structures, often found in miniaturized liquid crystal devices, are also treated. This book provides an inside look into light propagation in spatial varying anisotropic structures and helps the reader understand how to simulate the optical behavior correctly.
