Book National Military Establishments and the Advancement of Science and Technology

Download or read book National Military Establishments and the Advancement of Science and Technology written by P. Forman and published by Springer Science & Business Media. This book was released on 2001-11-30 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: To some philosophers, seeking to understand the human condition, technology is a necessary guide. But to think through the complex human phenomenon of technology we must tackle philosophy of science, philosophy of culture, moral issues, comparative civilizational studies, and the economics of specific industrial and military technologies in their historical contexts. The philoso pher wants to grasp the technological factor in this troubled world, even as we see it is only one factor, and that it does not speak openly for itself. Put directly, our human troubles to a considerable extent have been transformed, exaggerated, distorted, even degraded, perhaps transcended, by what engi neers and scientists, entrepreneurs and politicians, have wrought. But our problems are ancient, problems of dominations, struggles, survival, values in conflict, greed and insane sadisms. To get some conceptual light on the social reality which seems immediately to be so complicated, a philosopher will need to learn from the historians of technology. A few years ago, the philosopher Elisabeth Straker concluded that "a his torical philosophy of technology [is required] since history - and history alone - provides all those concepts that form part of the repertoire of the philosoph ical analysis of technology". And she added that this goes far beyond the triviality that like other cultural achievements technology has its historical development. Now historical comprehension is no substitute for a logical methodology in the analysis of technological problems.

Book Radiation from Variable reactance Surface wave Antennas

Download or read book Radiation from Variable reactance Surface wave Antennas written by M. G. Andreasen and published by . This book was released on 1961 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theoretical study is presented of the properties of flush-mounted or wo-sided ariablereac ance surface-wave a tennas. he paradox of radiation from a constant-reactance surfacewave antenna is discussed also in order to derive an understanding of the principle of radiati n from a surface-wave antenna with periodicallly varying parameters. The principle of radiation from Simon's cigar a tenna which has caused some controversy, is discussed. Finally, a theory, which i in principle exact, is developed for a variable-reactance surface-wave a tenna. By this theory, the surface field can be determined using a field representation in terms of couples cylindrical mode . For practical designs approximate expre sions for the surface field are derived. (author).

Book The Stripline Circulator

Download or read book The Stripline Circulator written by Joseph Helszajn and published by John Wiley & Sons. This book was released on 2008-05-16 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stripline circulator theory and applications from the world's foremost authority The stripline junction circulator is a unique three-port non-reciprocal microwave junction used to connect a single antenna to both a transmitter and a receiver. Its operation relies on the interaction between an electron spin in a suitably magnetized insulator with an alternating radio frequency magnetic field. In its simplest form, it consists of a microwave planar gyromagnetic resonator symmetrically coupled by three transmission lines. This book explores the magnetic interaction involved in the stripline circulator's operation, the nature of the microwave resonator shape, and the network problem that arises in coupling the microwave resonator to the microwave circuit. The stripline circulator is an important device met across a wide range of industries, including wireless, military, radar, and satellite communications. The book's design tables are a unique feature, offering valuable design support. Written by an international authority on non-reciprocal microwave circuits and devices, the book is organized into logical blocks of chapters that focus on specific effects and circuit aspects of the stripline circulator. Among the highlights of coverage are: Spatial shape demagnetizing factors of magnetic insulators Standing wave solutions of wye gyromagnetic planar resonators Lumped element circulators Negative permeability tracking and semi-tracking circulators Four-port single-junction circulators Fabrication of very weakly and weakly magnetized microstrip circulators The final chapter explores important and continuing discrepancies between theoretical models and actual practice. For designers building circulators, isolators, and phase shifters; researchers working on the limitation of ferrite devices; and graduate students intending to work in the field, Dr. Helszajn's insights and perspectives are invaluable.
