Master's Thesis from the year 2001 in the subject Electrotechnology, grade: with distinction, City University London, 50 entries in the bibliography, language: English, abstract: Bragg gratings are important devices for both optical communications and sensing. These devices are used to design very narrow band optical filters, which can be used in wavelength division multiplexing (WDM). It is also perceived that Bragg gratings will be used to compensate the dispersion in modern fibre optic telecommunication networks. Semiconductor gratings are usually integrated into lasers to control the operating wavelength. City University Photonic Modelling Group is a world leading research group on the use of rigorous numerical techniques to design and optimise advanced photonic devices for optical communications. The research group has already achieved results on hypothetical one-dimensional (1-D) and realistic two-dimensional (2-D) structures. In this project a combination of three numerical methods has been used, all of which are rigorous, to simulate realistic three-dimensional (3-D) structures in semiconductor waveguides. The combination of these three accurate methods, the finite element method (FEM), the least squares boundary residual (LSBR) method and the transfer matrix method (TMM) turned out to be superior to the widely used coupled mode theory (CMT). The numerical study of different Bragg gratings shows interesting dependencies of the characteristics of the gratings on the different design parameters. The work was carried out for different mesh distributions, different numbers of mesh divisions and different computational parameters. Another focus of the work was on the stability of the transmission and reflection coefficients obtained from the LSBR program. Furthermore the effect of inaccuracy occurring during the fabrication process has been studied. The results of this work have been compared to results found by other groups and fellows. We can say that this proj

The increasing global concerns about carbon emission and secure energy generation spurred a renewed interest in nuclear energy, alongside with development of advanced nuclear reactor designs and fuel cycles. This book proposes several solutions to improve the cycle of a Light Water Reactor (LWR). It focuses in particular on development of fuel cycles and operational strategies for the International Reactor Innovative and Secure (IRIS), an advanced LWR with integral design developed by an international consortium led by Westinghouse. The solutions proposed combine proven LWR technology with innovative engineering, therefore enabling IRIS, and the larger class of advanced LWRs, to meet aggressive licensing schedule without forgoing key economic and safety requirements for the fuel cycle of an advanced plant. Since the study has been performed through a joint collaboration with the nuclear industry, focus is maintained not only on the quality and innovation of the solutions proposed but also on their effective applicability in the near future. For these reasons, this book will appeal both the researcher and the engineer interested in the future of the nuclear energy.

This book describes VHF and UHF antennas for the range 30-3000 MHz developed over the last 50 years. Many designs that have not previously been described in detail are covered. The author's long, practical experience is shown in numerous examples of new uses for old designs. Particular attention is paid to the effects on the antennas of the local environment and the structures on which they are mounted, both fixed and mobile, including man. Methods of predicting and measuring the performance of antennas are described at length. The effect of adverse environments on antennas are discussed, and suggestions are given for measruing electrical performance under these conditions. The book is primarily aimed at practising antenna engineers - the theory of basic antennas is kept to a minimum but given where appropriate for the less well-known types.

A detailed account of Rife's inventions and discoveries is the subject of The Cancer Cure That Worked. This startling book documents events from 1913 to the time of Rife's death in 1972. Rife was an optical engineer and technician of great skill. His first success was the building of the Universal Microscope in the late 1920s. With it he was able to view the living cancer virus -- a feat our modern, high-powered electron microscopes still cannot do. His microscope used many quartz prisms and lenses, placed to compensate for losses of refraction due to air. This enabled him to view far tinier particles than had ever been seen before.
Using the Universal Microscope which he invented, he observed cancer viruses as they changed their size and form. He discovered that exposing a virus to certain frequencies of radio waves killed it quickly. Years of experimentation led to Rife's invention of the Frequency Instrument, a device that produced the exact frequencies needed to destroy various viruses.
In 1934 at the clinic in California, diseased people were exposed to the exact same frequencies that had been seen (through the microscope) to destroy the virus causing their illness. Treatments lasted only three minutes. The person would wait three days before another exposure giving the lymph system time to cleanse the dead virus from their bodies. Unlike the chemotherapy treatments currently in use, Rife's therapy was 100 percent effective and engendered no adverse symptoms.
Yet, 53 years after the arrival of Rife's Frequency Instrument, hundreds of thousands of people still die each year of diseases that Royal Raymond Rife cured.
