This book was released on 2012-12-06 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 22 (thesis year 1977) a total of 10,658 theses titles from 28 Canadian and 227 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. While Volume 22 reports theses submitted in 1977, on occasion, certain universities do report theses submitted in previous years but not reported at the time.
Download or read book Wideband Transition with Microstrip and CPW and Directional Coupler with Microstrip and CPW written by Swapna Male and published by . This book was released on 2010 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Directional couplers are often used in microwave systems to combine or divide RF signals. Usually, directional couplers are designed with the same transmission line technology like all microstrip lines or all CPW transmission lines. However, here we present a directional coupler using two different transmission line technologies. Therefore, the second part presents design of directional coupler with a combination of microstrip and CPW. The proposed directional coupler uses one single dielectric substrate. This is unlike similar directional coupolers that use the microstrip line technology, but with two stacked dielectric substrates. In order to develop the design equations for the directional couopler with combination of microstrip and CPW, which is not a symmetrical structure, the characteristic impedance and coupling factor expressions for the asymmetrical structure are derived and verified. Desired dimensions of the coupling section for 3dB coupling and 50 Ohms characteristic impedance are estimated by numerical interpolation. Finally, the coupler with microstrip and CPW is designed. Good coupling characteristics were achieved and verified with different simulation softwares like IE3D and HFSS.

Available in PDF, EPUB and Kindle. Book excerpt: A single text that incorporates all of the theoretical principles and practical aspects of planar transmission line devices - since the early development of striplines, it has been sought by countless microwave engineers, researchers, and students. With the publication of Networks and Devices Using Planar Transmission Lines, the search for that one authoritative resource is over. This is more than just a handbook, much more than a theoretical treatment. It's the ideal integration of the theory and applications of planar transmission lines and devices. Striplines, microstrips, slot lines, coplanar waveguides and strips, phase shifters, hybrids, and more - the author examines them all. For each type of structure, his treatment is complete and self-contained, including: Geometric characteristics Electric and magnetic field lines Solution techniques for the electromagnetic problem Quasi-static, coupled modes, and full wave analysis methods Design equations Attenuation Practical considerations Of particular interest is the author's comprehensive treatment of planar ferrimagnetic devices, such as phase shifters, isolators, and circulators, and three appendices dedicated to the theoretical aspects of ferrimagetism. Five other appendices provide thorough reviews of various theoretical concepts implicit in the body of the work, such as wave theory, the external properties of networks, and resonant circuits.

Download or read book Frequency Independent Antennas written by Victor H. Rumsey and published by Academic Press. This book was released on 2014-06-28 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Frequency Independent Antennas provides a reasonably complete coverage of frequency independent antennas from its inception until the middle of 1965. Most of the contents have not previously been published, except in scattered journal articles, and some are original. The first six chapters are written at a fairly easy level—about the level of a beginning graduate student or the more advanced undergraduate. The last two chapters, which deal with solutions of Maxwell's equations, are at a somewhat higher level. The book opens with a discussion of some fundamental ideas about antennas. It shows how typical measurements can be understood in terms of classical electromagnetic theory: in other words, how to make sense of measured data, how to set up apparatus to get meaningful data, and how to test their significance. Separate chapters follow on the features of frequency independent, plane-sheet, spiral, and log-periodic antennas. Subsequent chapters discuss how the periodic structure theory provides a way of understanding the peculiarities of frequency independent antennas; and solutions of Maxwell's equations for idealized spiral and idealized sinusoidal structures.

Download or read book Multiresonator Based Chipless RFID written by Stevan Preradovic and published by Springer Science & Business Media. This book was released on 2011-12-26 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: This vital new resource offers engineers and researchers a window on important new technology that will supersede the barcode and is destined to change the face of logistics and product data handling. In the last two decades, radio-frequency identification has grown fast, with accelerated take-up of RFID into the mainstream through its adoption by key users such as Wal-Mart, K-Mart and the US Department of Defense. RFID has many potential applications due to its flexibility, capability to operate out of line of sight, and its high data-carrying capacity. Yet despite optimistic projections of a market worth $25 billion by 2018, potential users are concerned about costs and investment returns. Clearly demonstrating the need for a fully printable chipless RFID tag as well as a powerful and efficient reader to assimilate the tag’s data, this book moves on to describe both. Introducing the general concepts in the field including technical data, it then describes how a chipless RFID tag can be made using a planar disc-loaded monopole antenna and an asymmetrical coupled spiral multi-resonator. The tag encodes data via the “spectral signature” technique and is now in its third-generation version with an ultra-wide band (UWB) reader operating at between 5 and 10.7GHz.
