This book focuses on the key technologies supporting orbital-angular-momentum multiplexing communication: generation, transmission, detection, and application of vortex beams. A series of methods for generating vortex beams are described and compared in detail. Laguerre-Gaussian and Bessel-Gaussian beams are taken as examples to introduce the transport properties of vortex beams in atmospheric turbulence. The authors show that superposition of vortex beam state, interference, diffraction, and grating can realize the detection of the topological charge of vortex beams. The authors also introduce the application of vortex beams in optical communication and the transmission characteristics of partially coherent vortex beams in atmospheric turbulence. Finally, the authors describe vortex beam information exchange and channel reconstruction.

This book gives insight into the theoretical backgrounds of optical vortices and their propagation in free space and simple optical systems. The author’s theoretical analysis allows full comprehension of recent results and allows a bridge between the mentioned topics. For example, there is a solution for an accelerating beam propagating along an almost half-circle, obtained from a solution for an asymmetric vortex Bessel mode. And vice versa, there is a solution for an optical vortex with accelerating focusing, obtained from a solution for a two-dimensional accelerating Pearcey beam. The book is intended for graduate and postgraduate students studying optics or wave physics.

This is presently the best available source on design and optimization of particle factories using e e - circular accelerators at the same time givingthe physical background for their construction. It addresses scientists and graduate students which is clearly reflected in its pedagogical style. The book aims at summarizing all the currently available knowledge on the motivation to construct particle factories, the design considerations of each of the different machine options including their lattices and interaction regions, practical details of the major systems constituting the machines, as well as a wide view of possible factories worldwide. It is the most up-to-date and unique collection of information of particle factories presently available.

This extended and revised second edition elaborates on techniques for the numerical analysis of beams, long strips, circular plates, and circular-cylindrical tanks resting on elastic foundations and on unyielding or elastic supports. Emphasis is placed on the simplicity of analysis, while maintaining the accuracy of results, and a large number of examples are included as illustration. Easy-to-use, fully-revised software is included which runs smoothly under current Windows operating systems. The applicability of the software is extended to analysis of laterally-loaded piles and bending analysis of retaining walls. A bonus suite of complementary software containing programmes for elastic-plastic soil-structure interaction analyses of beams or strips, laterally-loaded piles or sheet-piles, and long retaining walls is also included. This package of numerical techniques and software provides a powerful tool which renders design analysis of structures easy and time-efficient. Practising engineers will find this title invaluable, while postgraduate students and researchers working in soil-structure interaction will also find the book-software package very useful.
