Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Structurally disordered solids are characterized by their lack of spatial order that is evidenced by the great variety of ordered solids. The former class of materials is commonly termed amorphous or glassy, the latter crystalline. However, both classes share, many of the other physical properties of solids, e. g. , me chanical stability, resistance to shear stress, etc. The traditional macroscopic distinction between the crystalline and the glassy states is that while the former has a fixed melting point, the latter does not. However, with the availability and production of a large number of materials in both crystalline and amorphous states, and their easy inter-convertability, simple de finitions are not possible or at best imprecise. For the present purpose, it is sufficient to say that in contrast to the crystalline state, in which the posi tions of atoms are fixed into adefinite structure, ex cept for small thermal vibrations, the amorphous state of the same material displays varying degrees of de parture from this fixed structure. The amorphous state almost always shows no long range order. Short range order, up to several neighbors, may often be retained, although averaged considerably around their crystalline values. It is generally believed that the amorphous state is a metastable one with respect to the crystal line ordered state, and the conversion to the crystal line state may or may not be easy depending on the na ture of the material, e. g.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - In June 1978 the University of Rhode Island conducted a three-day short course on Recent Advances in Fiber Optics. followed by a two-day conference on the Physics of Fiber Optics. The course contained over a dozen lectures spanning a wide range of subject matter from fundamental theory to operational systems. presented by well-known scientists from industry. government and academic institutions. The conference. on the other hand. emphasized basic research on fiber optics and related subjects. This volume contains both papers presented at the conference. as well as the majority of the lectures from the course (the written versions were solicited on a voluntary basis for this volume). In some cases the papers in this volume represent expanded or otherwise modified versions of the original presentations. One of the principal aims of the conference was promulgation of novel and/or unconventional concepts. For this reason. the papers in this volume cover subjects such as bistable optical switches. fiber acoustic sensors. extruded infrared fibers. compressively coated glass fibers. and soliton propagation in fibers.
