Book Description
Advances in Microwaves, Volume 6 is a three-chapter text that explores the fundamental principles of precision coaxial connectors, traveling wave tubes, and junction circulators. Chapter 1 discusses the significant developments in the design, accuracy, and reference standard lines of precision coaxial connectors, with an emphasis on the application of the 7-mm and 14-mm precision coaxial connectors. Chapter 2 examines the stability of strongly modulated beams in a variety of focusing systems, such as uniform magnetic fields (Brillouin and near-Brillouin flow), linearly tapered magnetic fields, and periodic-permanent-magnet field systems. Chapter 3 deals with the theoretical aspects and characteristics of all types of junction circulators, with an emphasis on the lumped-element and the stripline circulator. Discussions on a theorem on passive three-port networks and star and delta networks are covered in the supplementary texts.

Book Description
Volume 54 of the Advances in Atomic, Molecular, and Optical Physics Series contains ten contributions, covering a diversity of subject areas in atomic, molecular and optical physics. The article by Regal and Jin reviews the properties of a Fermi degenerate gas of cold potassium atoms in the crossover regime between the Bose-Einstein condensation of molecules and the condensation of fermionic atom pairs. The transition between the two regions can be probed by varying an external magnetic field. Sherson, Julsgaard and Polzik explore the manner in which light and atoms can be entangled, with applications to quantum information processing and communication. They report on the result of recent experiments involving the entanglement of distant objects and quantum memory of light. Recent developments in cold Rydberg atom physics are reviewed in the article by Choi, Kaufmann, Cubel-Liebisch, Reinhard, and Raithel. Fascinating experiments are described in which cold, highly excited atoms ("Rydberg atoms) and cold plasmas are generated. Evidence for a collective excitation of Rydberg matter is also presented. Griffiin and Pindzola offer an account of non-perturbative quantal methods for electron-atom scattering processes. Included in the discussion are the R-matrix with pseudo-states method and the time-dependent close-coupling method. An extensive review of the R-matrix theory of atomic, molecular, and optical processes is given by Burke, Noble, and Burke. They present a systematic development of the R-matrix method and its applications to various processes such as electron-atom scattering, atomic photoionization, electron-molecule scattering, positron-atom scattering, and atomic/molecular multiphoton processes. Electron impact excitation of rare-gas atoms from both their ground and metastable states is discussed in the article by Boffard, Jung, Anderson, and Lin. Excitation cross sections measured by the optical method are reviewed with emphasis on the physical interpretation in terms of electronic structure of the target atoms. Ozier and Moazzen-Ahmadi explore internal rotation of symmetric top molecules. Developments of new experimental methods based on high-resolution torsional, vibrational, and molecular beam spectroscopy allow accurate determination of internal barriers for these symmetric molecules. The subject of attosecond and angstrom science is reviewed by Niikura and Corkum. The underlying physical mechanisms allowing one to generate attosecond radiation pulses are described and the technology needed for the preparation of such pulses is discussed. LeGouët, Bretenaker, and Lorgeré describe how rare earth ions embedded in crystals can be used for processing optically carried broadband radio-frequency signals. Methods for reaching tens of gigahertz instantaneous bandwidth with submegahertz resolution using such devices are analyzed in detail and demonstrated experimentally. Finally, in the article by Illing, Gauthier, and Roy, it is shown that small perturbations applied to optical systems can be used to suppress or control optical chaos, spatio-temporal dynamics, and patterns. Applications of these techniques to communications, laser stabilization, and improving the sensitivity of low-light optical switches are explored. - International experts - Comprehensive articles - New developments

Book Description
Physical Methods in Heterocyclic Chemistry, Volume VI discusses several topics including bond energies, electron-spin resonance, microwave spectroscopy, and photoelectron spectroscopy. This book explores the thermochemical applications to heterocyclic chemistry. Comprised of five chapters, this volume starts with an overview of the technique of photoelectron spectroscopy. This text then illustrates the various potentialities of photoelectron spectroscopy by discussing four examples taken from the field of heterocyclic compounds. Other chapters determine the magnitudes as well as the lines of action of electric dipole moments in the molecular framework. This book discusses as well the emission of light by individual molecules in solution, particularly heterocyclic molecules, which are electronically excited as a result of the absorption of visible or ultraviolet light. The final chapter deals with the aspects of heats of combustion, heats of hydrogenation, heats of formation, and bond energies. Heterocyclic chemists, chemists, biochemists, molecular biologists, and researchers will find this book extremely useful.

Book Description
The 9th International Workshop on "Laser Interaction and Related Plasma Phenomena" was held November 6-10, 1989, at the Naval Postgraduate School, Monterey, Cal ifornia. Starting in 1969, thi s represents a continuation of the longest series of meetings in this field in the United States. It is, in fact, the longest series anywhere with published Proceedings that document the advances and the growth of this dynamic field of physics and technology. Following the discovery of the laser in 1960, the study of processes involved in laser beam interactions with materials opened a basically new dimension of physics. The energy densities and intensities generated are many orders of magnitude beyond those previously observed in laboratories. Simultaneously, the temporal dynamics of this interaction covers a broad range, only recently reaching ultra short times, of the order of a few femtoseconds. Applications of this technology are of interest for many types of material treatments. Further, from the very beginning, a key ambitious goal has been to produce fusion energy by intense laser irradiation of a target containi ng appropriate fusion fuels. The vari ous phenomena discovered during the ensuing research on laser-fusion are, indeed, much more complex than originally expected. However, in view of recent advances in physics understanding, a route to successful laser fusion can be seen. The development of fusion energy received a very strong stimulation since the last workshop due to the now partially publicized results of underground nuclear explosions.

Book Description
Applied Optics and Optical Engineering, Volume VI is an 11-chapter text that covers the principles and design of some optical devices and systems. The first three chapters deal with the principles, mode of operation, and application of several types of lasers, such as solid-state, gas, and semiconductor diode lasers. These topics are followed by the presentation of the physics and engineering of acousto-optic systems and coherent light valves. A chapter provides the fundamental considerations of the principles of scanning devices and systems, including the light beam, the scanning motions and patterns, and optical, mechanical, and electronic engineering considerations. The discussion then shifts to the potential applications of coherent optical processing techniques in mapping and the infrared detectors to the optical engineer. The remaining chapters examine the principles and applications of optical holography, image intensifiers, and fiber optics. This book is of great benefit to applied scientists and engineers who are interested in the conceptualization and design of new instruments and systems of coherent optics.
