R6,264 Discovery Miles 62 640 Ships in 12 - 17 working days

Recent advances in technology have led to the unprecedented accuracy in measurements of endogenous electric fields around sites of tissue disruption. State-of-the-art molecular approaches demonstrate the role of bioelectricity in the directionality and speed of cell migration, proliferation, apoptosis, differentiation, and orientation. New information indicates that electric fields play a role in initiating and coordinating complex regenerative responses in development and wound repair and that they may also have a part in cancer progression and metastasis. Compiling current research in this rapidly expanding field, Physiology of Bioelectricity in Development, Tissue Regeneration, and Cancer highlights relevant, cutting-edge topics poised to drive the next generation of medical breakthroughs. Chapters consider methods for detecting endogenous electric field gradients and studying applied electric fields in the lab. The book addresses bioelectricity's roles in guiding cell behavior during morphogenesis and orchestrating higher order patterning. It also covers the response of stem cells to applied electric fields, which reveals bioelectricity as an exciting new player in tissue engineering and regenerative medicine. This book provides an in-depth exploration of how electric signals control corneal wound repair and skin re-epithelialization, angiogenesis, and inflammation. It also delves into the bioelectric responses of cells derived from the musculoskeletal system, bioelectrical guidance of neurons, and the beneficial application of voltage gradients to promote regeneration in the spinal cord. It concludes with a discussion of bioelectricity and cancer progression and the potential for novel cancer biomarkers, new methods for early detection, and bioelectricity-based therapies to target both the tumor and metastatic cancer cells. This multidisciplinary compilation will benefit biologists, biochemists, biomedical scientists, engineers, dermatologists, and clinicians, or anyone else interested in development, regeneration, cancer, and tissue engineering. It can also serve as an ideal textbook for students in biology, medicine, medical physiology, biophysics, and biomedical engineering.

"...Ben has been the world-wide guru of this technology, providing support to applications of all types. His genius lies in handling the extremely complex mathematics, while at the same time seeing the practical matters involved in applying the results. As this book clearly shows, Ben is able to relate to novices interested in using frequency selective surfaces and to explain technical details in an understandable way, liberally spiced with his special brand of humor... Ben Munk has written a book that represents the epitome of practical understanding of Frequency Selective Surfaces. He deserves all honors that might befall him for this achievement." -William F. Bahret.

Mr. W. Bahret was with the United States Air Force but is now retired. From the early 50s he sponsored numerous projects concerning Radar Cross Section of airborne platforms in particular antennas and absorbers. Under his leadership grew many of the concepts used extensively today, as for example the metallic radome. In fact, he is by many considered to be the father of stealth technology.

"This book compiles under one cover most of Munk's research over the past three decades. It is woven with the physical insight that he has gained and further developed as his career has grown. Ben uses mathematics to whatever extent is needed, and only as needed. This material is written so that it should be useful to engineers with a background in electromagnetics. I strongly recommend this book to any engineer with any interest in phased arrays and/or frequency selective surfaces. The physical insight that may be gained from this book will enhance their ability to treat additional array problems of their own." -Leon Peters, Jr.

Professor Leon Peters, Jr., was a professor at the Ohio State University but is now retired. From the early sixties he worked on, among many other things, RCS problems involving antennas and absorbers.

This book presents the complete derivation of the Periodic Method of Moments, which enables the reader to calculate quickly and efficiently the transmission and reflection properties of multi-layered Frequency Selective Surfaces comprised of either wire and/or slot elements of arbitrary shape and located in a stratified medium. However, it also gives the reader the tools to analyze multi-layered FSS's leading to specific designs of the very important Hybrid Radome, which is characterized by constant band width with angle of incidence and polarization. Further, it investigates in great detail bandstop filters with large as well as narrow bandwidth (dichroic surfaces). It also discusses for the first time, lossy elements used in producing Circuit Analog absorbers. Finally, the last chapter deals with power breakdown of FSS's when exposed to pulsed signals with high peak power.

The approach followed by most other presentations simply consists of expanding the fields around the FSS, matching the boundary conditions and writing a computer program. While this enables the user to obtain calculated results, it gives very little physical insight and no help in how to design actual multi-layered FSS's. In contrast, the approach used in this title analyzes all curves of desired shapes. In particular, it discusses in great detail how to produce radomes made of FSS's located in a stratified medium (Hybrid Radomes), with constant band width for all angles of incidence and polarizations. Numerous examples are given of great practical interest. More specifically, Chapter 7 deals with the theory and design of bandpass radomes with constant bandwidth and flat tops. Examples are given for mono-, bi- and tri-planar designs. Chapter 8 deals with bandstop filters with broad as well as narrow bandwidth. Chapter 9 deals with multi-layered FSS of lossy elements, namely the so-called Circuit Analog Absorbers, designed to yield outstanding absorption with more than a decade of bandwidth.

Application of the information in Introduction to Microwave Circuits will reduce design-cycle time and costs, markedly increasing the probability of first-time success in printed circuit or monolithic microwave integrated circuit (MMIC) design. Several approaches are taken into consideration, such as the effects of currents on the ground plane, bypass and coupling capacitors, and nonlinear effects in linear circuits. Featured topics include:
* Incorporation of component parasitics in the design cycle
* Closed form solution to oscillator design
* Odd mode stability analysis
* PIN diode analysis for high-power switching applications
An integrated design example of a 1.25 GHz amplifier, oscillator, and filter printed circuit is also included, which could be useful in printed circuit board designs from tens of megahertz to tens of gigahertz.

RF power amplifiers are implemented in communication, semiconductor wafer processing, magnetic resonance imaging (MRI), and radar systems to produce RF signal with the desired characteristics to perform several critical tasks in the entire system. They can be designed to operate in linear or switch-mode, depending on the specific application. This book explores the design and implementation methods for both linear and switch-mode amplifiers with real world engineering problems. The text discusses phased controlled switch-mode amplifiers and distortion and modulation effects in RF amplifiers. It illustrates the interface and integration of components and sub-systems for RF amplifiers. The material is further reinforced with MATLAB design files.
