Birefringent Thin Films and Polarizing Elements (2nd Edition) includes the significant advances that have been made since the first book on tilted-columnar films was published. The major discovery of serial bideposition has led to a normal-columnar nanostructure with enhanced birefringence and in turn to nanoengineered handed films with properties matching the left-circular reflectors of scarab beetles. A second version of the Matlab software that accompanies the book includes algorithms for computing material, electromagnetic and optical properties of isotropic, birefringent and chiral films. A set of numerical and experimental examples chosen to illustrate and generate interest in these new fields will be of interest to graduate students and to researchers in optics.
