This book was released on 1997-04-11 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: A detailed and timely overview of recent developments in active quasi-optical arrays In recent years, active quasi-optics has emerged as one of the most dynamic fields of contemporary research—a highly unconventional approach to microwave and millimeter-wave power generation that integrates solid-state devices into a single quasi-optical component in which all devices operate in unison. This book defines and describes active quasi-optical arrays, reviews the current state of the art, and answers numerous basic and technical questions on the design, analysis, and application of these devices. The contributors to this volume are leading researchers in the field who present results and views from government, industrial, and university laboratories and offer a balanced discussion on a high technical level. They also offer insight into the applicability and commercial value of this technology for military systems, manufacturing processes, communications, and consumer products. Topics presented include: Analysis and design methodologies for quasi-optical active arrays Power-added and power-combining efficiencies of quasi-optical amplifier arrays Phase-shifterless beam steering in oscillator and amplifier arrays Integrating quasi-optical active components into a compact subsystem Design and fabrication of quasi-optical oscillators, amplifiers, multipliers, and tuners Characterization and measurement of quasi-optical components

This book was released on 2006 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: The next generation of space observatories will use larger mirrors while meeting tighter optical performance requirements than current space telescopes. The spacecraft designs must satisfy the drive for low-mass, low-cost systems, and be robust to uncertainty since design validation will be based on analysis instead of pre-launch tests. Analytical techniques will be required to identify which technologies or structural architectures are most appropriate to meet conflicting system requirements, but traditionally, model-based dynamic analysis would only take place after a single point design is chosen. The challenges facing future space telescopes require a new approach to conceptual design, and motivate the creation of design tools to identify superior, robust designs earlier in the design lifecycle using model-based analysis methods. A conceptual design methodology is proposed, in which both nominal performance as well as robustness to uncertainty are evaluated across multiple design realizations. A modeling environment is created so that for any set of design variables, such as mirror architecture or dimensions of the spacecraft, a finite element model is automatically generate and analyzed.

Download or read book Opto structural Analysis written by John W. Pepi and published by . This book was released on 2018 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents basic structural deformation and stress analysis as applied to optical systems. It provides the tools for first-order analyses required in the design concept phase before handling the intricate details of a full-up design. While finite element analysis is paramount to a successful design, the purpose of this text is not to use finite element analysis to validate the hand analysis, but rather to use hand analysis to validate the finite element models. The hand analysis forces a discipline that is paramount in the understanding of structural behavior. Presuming that the reader has a working knowledge in the strength of materials, the text applies engineering principles to opto-structural analysis.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: With the emergence of high power, millimeter wave sources operating at 94 GHz and 220 GHz with output powers in excess of 10 kW and 50 W, respectively, creates a critical need to route and process these powers efficiently. Since fundamental mode waveguides become unreasonably lossy and run into the breakdown regime to handle these associated powers when operating at the millimeter wave to terahertz regime, quasi-optical techniques, which utilize higher beam modes and common optical techniques, are employed. Such techniques typically require stringent mode control and call for intercoupling wave propagation analysis to minimize mode conversion. These complicated analysis techniques stretch the capabilities of traditional differential equation formulations typically employed to analysis complex structures in the microwave regime. Additionally, these structures become electrically large due to the shrinking associated wavelengths of the propagating waves in the millimeter wave to terahertz spectrum making such analysis difficult-to-impossible under 'normal' computing conditions. To intelligently design and manufacture these components, the multiphysics behavior of these devices must be carefully understood. As a result, circuit models and quick solver methodologies are presented and used to analyze these electrically large systems. As a result of careful signal integrity engineering, quasi-optical components and systems are designed and the experimental results are presented to extract empirical values, benchmark numerical solutions, and for practical use. As a result of these studies, one can conclude that quasi-optical signal processing and overmoded transmission line systems are essential to efficiently process the high powers fields radiating from the described vacuum electron beam devices for next generation telecommunication, remote sensing, scientific instrumentation, and electronic warfare systems.
