The book consists of two Volumes. The first (the preceding volume) is devoted to the general nonlinear theory of the hierarchical dynamic oscillative-wave systems. This theory has been called the theory of hi- archical oscillations and waves. Here two aspects of the proposed theory are discussed. The first aspects concern the fundamental nature and the basic c- cepts and ideas of a new hierarchical approach to studying hierarchical dynamic systems. A new hierarchical paradigm is proposed as a - sis of a new point of view of such types of systems. In turn, a set of hierarchical principles is formulated as the fundamental basis of this paradigm. Therein the self-resemblance (holographic) principle plays a key role here. An adequate mathematic description (factorization) of the proposed paradigm is carried out. The concepts of structural and dynamic (functional) operators are put into the basis of this descr- tion. Electrodynamics is chosen as a convenient basis for an obvious demonstration of some key points of the proposed new theory. The second aspect has a purely mathematical nature. It is related to the form of factorization (i.e., mathematical description) of hier- chical types of dynamic models, and discussion of the methods of their mathematical analysis. A set of the hierarchical asymptotic analytical- numerical methods is given as an evidence of the practical effectiveness of the proposed version of hierarchical theory.

This book is the result of the contributions coming from the more than thirty key rd speakers of the 3 international Workshop on Nonlinear Microwave Magnetics held in th Roma, Italy from the 3rd to the 6 of October 1995. Since the 1990, in Ulyanovsk, when the Russian Academy of Sciences promoted the first Workshop of the series, the basic idea was to have a sort of Institutional Meeting collecting Scientists of the Magnetics Community devoted to Spin Wave Electronics at Microwave Frequencies. It was a succesful organization, and the birth of an effective interaction between eastern and western researchers overcame the meaning of the Workshop itself. Three years later, in Irvine, California, 1993, the Spin Wave Community was joined again. It was clear that the growing interest on hot topics of Nonlinear Microwave Magnetics involving both, applicative and fundamental aspects of microwave magnetic media, favoured the organization of further meetings on the same subject. So far, during the social dinner, in the middle between a serious proposal and the joke encouraged by the Californian Wine, Roma was proposed as the third place for the Workshop. Day after day, the joke became serious, and it was possible to solve the financial and logistic problems in time for the predicted deadline.

The Handbook of Modern Ferromagnetic Materials is an up-to-the-minute compendium of all ferromagnetic materials, metallic and ceramic, intended for electrical and electronic applications. Coverage of the newest and most economically important materials (soft ferrites, the rare-earth magnet alloys, amorphous and nanocrystalline alloys) is extensive. The distinctive feature of this book is its correlation of basic material properties (metallurgical and ceramic) with their magnetic characteristics and eventually to the choice in an application. Unique to this work is information on the many magnetic components into which these materials can be formed and the pertinent design data. Another useful feature is the criteria (quality, stability and economic) for selection of a particular material. Included are the mechanical, thermal and physical properties of these materials. The author not only presents the latest information from suppliers and magnetism conferences but includes a section on new materials (e.g. colossal magnetostriction materials) being developed but not yet available.The format is arranged according to frequency of operation, which turns out to be almost concurrent with the application. Thus, direct current applications are considered first, then low frequency line power, followed by applications at increasing frequencies up to microwave uses. This anthology of ferromagnetic materials is an essential reference work for electrical and electronic designers and materials scientists. It may also serve as a text for a magnetic materials course and as a materials guide for purchasing agents and technical executives.

The growth of Internet traf?c in recent years surpassed the prediction of one decade ago. Data stream in individual countries already reached terabit/s level. To cope with the petabit class demands of traf?c in coming years the communication engineers are required to go beyond the incremental improvement of today's technology. A most promising breakthrough would be the introduction of modulation f- mats enabling higher spectral ef?ciency than that of binary on-off keying scheme, virtually the global standard of ?ber-optic communication systems. In wireless communication systems, techniques of high spectral density modulation have been well developed, but the required techniques in optical frequency domain are much more complicated because of the heavier ?uctuation levels. Therefore the past trials of coherent optical modulation/detection schemes were not successful. However, the addition of high-speed digital signal processing technology is the fundam- tal difference between now and two decades ago, when trials of optical coherent communication systems were investigated very seriously. This approach of digital coherent technology has attracted keen interest among communication specialists, as indicated by the rapid increase in the pioneering presentations at the post-deadline sessions of major international conferences. For example, 32 terabit/s transmission in a ?ber experiment based on this technology was reported in post-deadline session of Optical Fiber Communication Conference (OFC) 2009. The advancement of the digital coherent technologies will inevitably affect the network architecture in terms of the network resource management for the new generation photonic networks, rather than will simply provide with huge transmission capacity.
