Book Description
Allowing many chemical reactions to be completed within minutes, microwave heating has revolutionized preparative chemistry. As a result, this technology has been widely adopted in both academic and industrial laboratories. Integrating microwave-assisted chemistry into undergraduate laboratory courses enables students to perform a broader range of reactions in the allotted lab period. As a result, they can be introduced to chemistry that would otherwise have been inaccessible due to time constraints (for example, the need for an overnight reflux). Laboratory Experiments Using Microwave Heating provides 22 experiments encompassing organic, inorganic, and analytical chemistry performed using microwave heating as a tool, making them fast and easy to accomplish in a laboratory period. Utilizing the time-saving experiments described in this book also permits students to repeat experiments if necessary or attempt additional self-designed experiments during the lab course. A number of the chemical transformations use water as a solvent in lieu of classical organic solvents. This contributes to greener, more sustainable teaching strategies for faculty and students, while maintaining high reaction yields. All the experiments have been tested and verified in laboratory classes, and many were even developed by students. Each chapter includes an introduction to the experiment and two protocols—one for use with a smaller monomode microwave unit employing a single reaction vessel and one for use with a larger multimode microwave unit employing a carousel of reaction vessels.

Book Description
Using microwaves to treat metal-based materials is rapidly emerging as an energy-efficient tool to interact with metals for a number of processes such as sintering, melting, brazing, carburizing and annealing. Microwaves can sinter a wide variety of metal compacts with comparable or enhanced end properties, while at the same time delivering tremendous energy savings over conventional sintering. Microwave processes are therefore gaining increasing attention and adoption in both academia and industry. Gupta and Wong have written this comprehensive text to introduce readers to the world of microwaves and the interaction of microwaves with metals and metals-based formulations. The authors have combined numerous research results from a wide range of sources alongside their own work in the field. Also included are overviews of microwave heating of other non-metal materials and the equipment used for microwave-assisted metallurgy. With microwave techniques poised for widespread adoption, Microwaves and Metals is an essential text for all metallurgists and materials engineers. Provides a thorough grounding in microwave fundamentals and their application to metals processing Informs readers of the latest developments in the field Presents a convenient single source for all aspects of microwave processing of metals and materials Contains liberal illustration to compare and benchmark research results Introduces all the necessary equipment, preparing readers for real-world practice Microwaves and Metals is ideal for a post-graduate or advanced undergraduate course in materials science or metallurgy. Materials and metallurgical engineers in industry, who are keen on cheaper, faster techniques, will also benefit from this book.

Book Description
The concept of using electromagnetic energy in the form of microwaves for transferring power from one point to another through free space is very old. However, the idea for powering micro air vehicles using microwaves is less than a decade old. This thesis presents a theoretical and experimental study of powering a micro air vehicle, using electromagnetic energy at the frequency of 10 GHz. Two micro air vehicle prototypes were designed and built, and various experiments conducted in order to specify the power requirements of such a vehicle. The vehicle weighted 9-15 grams and its maximum dimension was six inches. The rectifier antenna (rectenna) is a major component in a microwave power transmission process. A quality factor used for rectenna characterization is the conversion efficiency from microwave power to DC power. A key component in any rectenna design is the Schottky barrier diode, which is used to rectify the microwave energy to DC energy. A small rectenna array was manufactured using sixteen identical elements. Each element consisted of a circular patch antenna, a rectifying diode, and input and output low pass filters. The circuit was tested and the results showed a 10.3% conversion efficiency of the individual rectenna element, and 8.2% conversion efficiency for the total circuit.

Book Description
"Do you want to design a wireless transmitter or receiver for hand-held telephones? Have you wondered why the printed circuit wires on high-frequency circuits don't always run in a straight line? This valuable text will answer all of your questions regarding component parasitics and circuit characterization for rf/microwave amplifier, oscillator, and filter circuit design and analysis. You will understand why capacitors act as inductors and vice versa and why amplifiers work like oscillators, while oscillators for local area networks work more like local area heaters. 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. Introduction to Microwave Circuits provides the tools necessary to analyze or synthesize microwave circuits. This text is an essential reference for undergraduate students, microwave engineers, and administrators. Also, it will assist experienced designers in other fields to meet the current rapid expansion of communication system applications and work effectively in microwave circuit design. About the Author Robert J. Weber began his prolific career in the Solid State Research Laboratory at the Collins Radio Company, later a part of Rockwell International.
