The reports investigates the propagation of light in the visible region through a crystalline medium. In Part I, the objective is to determine if the anisotropic arrangement of ordinary (isotropic) dipoles at the nodal points of an orthorhombic lattice would account for the existence of double refraction. Some features of the traditional 'theory of dispersion' are disclosed and clarified. In part II, a crystalline medium is considered as filling a half- space and having a plane boundary at z=0. A plane optical wave is incident on this medium. Because of the linearity of the equations it has to be superimposed on the field originating in the crystal. It is shown that this incident optical wave is actually prevented from entering the crystal because of the modification produced in the field of the crystal by the introduction of a boundary. Material Added 1970. The conclusion that the incident optical field cannot penetrate the crystal boundary, together with a similar conclusion in a paper by Oseen, is the basis of the Ewald-Oseen Extinction Theorem.

Optical second harmonic light scattering, or hyper-Rayleigh light scattering which is characterized by the electromagnetic radiation at the double frequency of an incident light in magnetic crystal with the single straight edge dislocation have been phenomenologically investigated by adopting a nonlinear photoelastic and a nonlinear magneto-optic interactions. The polarization dependencies of the light scattered at the double frequency of an incident light for the different scattering geometries are analyzed.

``Optical Properties of Mixed Crystals'' is concerned with the description of optical processes in substitutionally disordered semiconductors and insulators which can be basically described through their elementary excitations. Two of the chapters relate to the phonon response including the effect of side bands on electron transitions. Two relate to electronic spectra, one on photoelectron spectroscopy and the other on excitons. A further chapter deals with magnons in magnetic crystals and a final chapter is related to fluctuations and band edge effects.Each chapter deals with a specific class of excitation, but the book makes it clear that the fundamental structure of the excitation spectra, including band formation, band tailing and localisation is common to every type of excitation. The volume shows how some basic concepts and ideas can be widely applied to bring coherence and understanding to a diverse area of solid state physics. It therefore provides an up-to-date summary of the experimental and theoretical situation in an important and rapidly developing field and brings together for the first time a discussion of the many different types of spectra which appear in mixed crystals.

Since their inception more than 2.5 years ago, photon correlation techniques for the spatial, temporal or spectral analysis of fluctuating light fields have found an ever-widening range of applications. Using detectors which re spond to single quanta of the radiation field, these methods are intrinsically digital in natnre and in many experimental situations offer a unique degree of accuracy and sensitivity, not only for the study of primary light sources themselves, but most particularly in the use of a laser-beam probe to study light scattering from pure fluids, macromolecular suspensions and laminar or turbulent flowing fluids and gases. Following the earliest developments in laser scattering by dilute macro nl01ecular suspensions, in , ... hich particle sizing was the main aim, and the use of photon correlation techniques for laser-Doppler studies of flow and tnrbuence. both of which areas were the subject of NATO ASls in Capri, Italy in 19;:3 and 19;6. significant advances have be('n made in recent years in many other areas. These were reflected in the topics covered in this NATO Advanced Research Workshop, which took place from August 2;th to 30th, 1!)!}6, at the Jagiellonian University, Krakow, Poland. These in cluded ('xperimental techniques. statist.ics and data reduction, colloids and aggregation, polymers, gels, liquid crystals and mixtures, protein solutions, critical pllf'nomena and dense media.

A few years ago in photorefractive crystals of LiTaO3:Cu (1) and LiNbO 3:Cu (2) a new nonlinear optic phenomenon, called the parametric scattering of 'holographic type', has been observed. As in the case of well-known (3) wide-angle species of photoinduced scattering, this process was degenerate. But it occurred under condition of phase-matching for four coupling waves: 2K sub L(omega)=K sub s1(omega) + K sub s2(omega) and hence had narrow spatial spectrum, where K sub L, K sub s1, K sub s2 are the are the S2 wave vectors of the pump and two phase-conjugated scattered waves on frequency omega. The scattered radiation was polarized orthogonally in respect to the laser beam.

The International Conference on Light Scattering Spectra of Solids was held at New York University on September 3, 4, 5, 6, 1968. The Conference received financial support from the U. S. Army Research Office (Durham), The New York State Science and Technology Foundation, the U. S. Office of Naval Research, and The Graduate School of Arts and Sciences of New York University. Co-sponsoring the Conference was the International Union of Pure and Applied Physics. The initial conception for the Light Scattering Conference arose from informal discussions held by Professor Eli Burstein, Professor Marvin Silver (representing the U. S. Army Research Office) and Professor Joseph Birman, late in 1966. In early discussions a format was put forth for a meeting to be held the following year, re viewing the state of the art, and emphasizing novel developments which had 9ccurred since the 1965 International Colloquium on Scattering Spectra of Crystals held in Paris (proceedings published in Le Journal de Physique, Volume 26, November 1965).

Photonic technology promises much faster computing, massive parallel processing, and an evolutionary step in the digital age. The search continues for devices that will enable this paradigm, and these devices will be based on photonic crystals. Modeling is a key process in developing crystals with the desired characteristics and performance, and Electromagnetic Theory and Applications for Photonic Crystals provides the electromagnetic-theoretical models that can be effectively applied to modeling photonic crystals and related optical devices. The book supplies eight self-contained chapters that detail various analytical, numerical, and computational approaches to the modeling of scattering and guiding problems. For each model, the chapter begins with a brief introduction, detailed formulations of periodic structures and photonic crystals, and practical applications to photonic crystal devices. Expert contributors discuss the scattering matrix method, multipole theory of scattering and propagation, model of layered periodic arrays for photonic crystals, the multiple multipole program, the mode-matching method for periodic metallic structures, the method of lines, the finite-difference frequency-domain technique, and the finite-difference time-domain technique. Based on original research and application efforts, Electromagnetic Theory and Applications for Photonic Crystals supplies a broad array of practical tools for analyzing and designing devices that will form the basis for a new age in computing.
