This book was released on 2004 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dynamics of wave propagation in media with negative index of refraction is analyzed through analytical calculations, simulations, and experiments. For passive media, the circumstances under which the real part of the index can be negative are investigated. Several models for media exhibiting negative refractive index are studied and the transmission characteristics of these media are calculated analytically. It is shown that these models suggest the existence of abnormal group velocity and abnormal group delay bands. Furthermore, the presence of abnormal group delay behavior in several existing Left-Handed Media (LHM) is discovered and analyzed using full wave simulations. Using a free space setup, the transmission characteristics of two split ring resonator and strip wire LHM, designed for operation at K-band frequencies (18--26GHz), are measured. The first LHM, which is 3 unit cells long in the propagation direction, exhibits a maximum negative group delay of -0.9ns whereas the second LHM (4 unit cells long) exhibits a maximum negative group delay of -1.2ns. For both LHM the bandwidth of the negative group delay region was approximately 250MHz.

Available in PDF, EPUB and Kindle. Book excerpt: With a novel, less classical approach to the subject, the authors have written a book with the conviction that signal processing should be taught to be fun. The treatment is therefore less focused on the mathematics and more on the conceptual aspects, the idea being to allow the readers to think about the subject at a higher conceptual level, thus building the foundations for more advanced topics. The book remains an engineering text, with the goal of helping students solve real-world problems. In this vein, the last chapter pulls together the individual topics as discussed throughout the book into an in-depth look at the development of an end-to-end communication system, namely, a modem for communicating digital information over an analog channel.

Available in PDF, EPUB and Kindle. Book excerpt: Of all measurement units, frequency is the one that may be determined with the highest degree of accuracy. It equally allows precise measurements of other physical and technical quantities, whenever they can be measured in terms of frequency. This volume covers the central methods and techniques relevant for frequency standards developed in physics, electronics, quantum electronics, and statistics. After a review of the basic principles, the book looks at the realisation of commonly used components. It then continues with the description and characterisation of important frequency standards from atomic clocks, to frequency stabilised lasers. The whole is rounded of with a discussion of topical applications in engineering, telecommunications, and metrology.

Available in PDF, EPUB and Kindle. Book excerpt: In February 1999, only a few weeks before the U.S. Air Force spearheaded NATO's Allied Force air campaign against Serbia, Col. C.R. Anderegg, USAF (Ret.), visited the commander of the U.S. Air Forces in Europe. Colonel Anderegg had known Gen. John Jumper since they had served together as jet forward air controllers in Southeast Asia nearly thirty years earlier. From the vantage point of 1999, they looked back to the day in February 1970, when they first controlled a laser-guided bomb strike. In this book Anderegg takes us from "glimmers of hope" like that one through other major improvements in the Air Force that came between the Vietnam War and the Gulf War. Always central in Anderegg's account of those changes are the people who made them. This is a very personal book by an officer who participated in the transformation he describes so vividly. Much of his story revolves around the Fighter Weapons School at Nellis Air Force Base (AFB), Nevada, where he served two tours as an instructor pilot specializing in guided munitions.

Available in PDF, EPUB and Kindle. Book excerpt: During a century, from the Van der Waals mean field description (1874) of gases to the introduction of renormalization group (RG techniques 1970), thermodynamics and statistical physics were just unable to account for the incredible universality which was observed in numerous critical phenomena. The great success of RG techniques is not only to solve perfectly this challenge of critical behaviour in thermal transitions but to introduce extremely useful tools in a wide field of daily situations where a system exhibits scale invariance. The introduction of scaling, scale invariance and universality concepts has been a significant turn in modern physics and more generally in natural sciences. Since then, a new "physics of scaling laws and critical exponents", rooted in scaling approaches, allows quantitative descriptions of numerous phenomena, ranging from phase transitions to earthquakes, polymer conformations, heartbeat rhythm, diffusion, interface growth and roughening, DNA sequence, dynamical systems, chaos and turbulence. The chapters are jointly written by an experimentalist and a theorist. This book aims at a pedagogical overview, offering to the students and researchers a thorough conceptual background and a simple account of a wide range of applications. It presents a complete tour of both the formal advances and experimental results associated with the notion of scaling, in physics, chemistry and biology.

Space and time discretizing time domain methods for electromagnetic full-wave simulation have emerged as key numerical methods in computational electromagnetics. Time domain methods are versatile and can be applied to the solution of a wide range of electromagnetic field problems. Computing the response of an electromagnetic structure to an impulsive excitation localized in space and time provides a comprehensive characterization of the electromagnetic properties of the structure in a wide frequency range. The most important methods are the Finite Difference Time Domain (FDTD) and the Transmission Line Matrix (TLM) methods. The contributions represent the state of the art in dealing with time domain methods in modern engineering electrodynamics for electromagnetic modeling in general, the Transmission Line Matrix (TLM) method, the application of network concepts to electromagnetic field modeling, circuit and system applications and, finally, with broadband devices, systems and measurement techniques.

Book excerpt: Challenging the popular myth of a present-day 'information revolution', Media Technology and Society is essential reading for anyone interested in the social impact of technological change. Winston argues that the development of new media forms, from the telegraph and the telephone to computers, satellite and virtual reality, is the product of a constant play-off between social necessity and suppression: the unwritten law by which new technologies are introduced into society only insofar as their disruptive potential is limited.

Book excerpt: Dedicated to the Sailors and Marines who lost their lives on the final voyage of USS Indianapolis and to those who survived the torment at sea following its sinking. plus the crews that risked their lives in rescue ships. The USS Indianapolis (CA-35) was a decorated World War II warship that is primarily remembered for her worst 15 minutes. . This ship earned ten (10) battle stars for her service in World War II and was credited for shooting down nine (9) enemy planes. However, this fame was overshadowed by the first 15 minutes July 30, 1945, when she was struck by two (2) torpedoes from Japanese submarine I-58 and sent to the bottom of the Philippine Sea. The sinking of Indianapolis and the loss of 880 crew out of 1,196 --most deaths occurring in the 4-5 day wait for a rescue delayed --is a tragedy in U.S. naval history. This historical reference showcases primary source documents to tell the story of Indianapolis, the history of this tragedy from the U.S. Navy perspective. It recounts the sinking, rescue efforts, follow-up investigations, aftermath and continuing communications efforts. Included are deck logs to better understand the ship location when she sunk and testimony of survivors and participants. For additional historical publications produced by the U.S. Naval History and Heritage Command, please check out these resources here: https://bookstore.gpo.gov/agency/naval-history-heritage-command Year 2016 marked the 71st anniversary of the sinking and another spike in public attention on the loss -- including a big screen adaptation of the story, talk of future films, documentaries, and planned expeditions to locate the wreckage of the warship.
