This book presents a novel, automated, accurate and unified scheme to design and determine the performance characteristics of standalone planar, spiral inductors and multiple coupled planar spiral inductors (as in embedded transformers), for RF/microwave MMIC designers. The author demonstrates with a set of analysis/design examples a novel scheme that exploits judiciously the existing transmission theory and concepts, organizing and condensing available, scattered information/knowledge about planar spiral inductor, embedded planar transformer and planar antenna design and performance evaluation, into one coherent and unified electronic circuit model easily used by radio frequency electronic circuit engineers. A dedicated chapter contains an exhaustive (19) set of design examples. Presents a bottom-up scheme, starting with Maxwell's equations of classical electrodynamics and transmission line theory (Telegrapher's equation), specifically microstrips; Demonstrates design of standalone planar, spiral inductors and multiple coupled planar spiral inductors; Includes a set of ready-to-use, C executables (for both Linux and Windows) , that accept predefined input parameters for each of the sub-circuits discussed and generate SPICE netlists for the equivalent electrical circuit; Automates execution of multi-step design calculations to guarantee their accuracy and reliability.

This book covers all aspects of the different classes of nanomaterials – from synthesis to application. It investigates in detail the use and feasibility of developing nanocomposites with these nanomaterials as reinforcements. The book encompasses synthesis and properties of cellulose nanofibers, bacterial nanocellulose, carbon nanotubes / nanofibers, graphene, nanodiamonds, nanoclays, inorganic nanomaterials and their nanocomposites for high-end applications such as electronic devices, energy storage, structural and packaging. The book also provides insight into various modification techniques for improving the functionality of nanomaterials apart from their compatibility with the base matrix.
This book gathers the Proceedings of the International Conference on Mechatronics and Intelligent Robotics (ICMIR2017), held in Kunming, China, on May 20–21, 2017. The book covers a total of 172 papers, which have been divided into seven different sections: Intelligent Systems, Intelligent Sensors & Actuators, Robotics, Mechatronics, Modeling & Simulation, Automation & Control, and Robot Vision. ICMIR2017 provided a vital forum for discussing the latest and most innovative ideas from both the industrial and academic worlds, and for sharing best practices in the fields of mechanical engineering, mechatronics, automatic control, electrical engineering, finite element analysis and computational engineering. The main focus of the conference was on promoting interaction between academia and industry, allowing the free exchange of ideas and challenges faced by these two key stakeholders and encouraging future collaboration between the members of these groups. The proceedings cover new findings in the following areas of research and will offer readers valuable insights: Mechatronics Intelligent mechatronics, robotics and biomimetics; Novel and unconventional mechatronic systems; Modeling and control of mechatronics systems; Elements, structures and mechanisms of micro and nano systems; Sensors, wireless sensor networks and multi-sensor data fusion; Biomedical and rehabilitation engineering, prosthetics and artificial organs; Artificial Intelligence (AI), neural networks and fuzzy logic in mechatronics and robotics; Industrial automation, process control and networked control systems; Telerobotics, Human–Computer Interaction; and Human–Robot Interaction. Robotics Artificial Intelligence; Bio-inspired robotics; Control algorithms and control systems; Design theories and principles; Evolutional robotics; Field robotics; Force sensors, accelerometers, and other measuring devices; Healthcare robotics; Human–Robot Interaction; Kinematics and dynamics analysis; Manufacturing robotics; Mathematical and computational methodologies in robotics; Medical robotics; Parallel robots and manipulators; Robotic cognition and emotion; Robotic perception and decisions; Sensor integration, fusion, and perception; and Social robotics.
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.

Up-to-date coverage of the analysis and applications of coplanar waveguides to microwave circuits and antennas The unique feature of coplanar waveguides, as opposed to more conventional waveguides, is their uniplanar construction, in which all of the conductors are aligned on the same side of the substrate. This feature simplifies manufacturing and allows faster and less expensive characterization using on-wafer techniques. Coplanar Waveguide Circuits, Components, and Systems is an engineer's complete resource, collecting all of the available data on the subject. Rainee Simons thoroughly discusses propagation parameters for conventional coplanar waveguides and includes valuable details such as the derivation of the fundamental equations, physical explanations, and numerical examples. Coverage also includes: Discontinuities and circuit elements Transitions to other transmission media Directional couplers, hybrids, and magic T Microelectromechanical systems based switches and phase shifters Tunable devices using ferroelectric materials Photonic bandgap structures Printed circuit antennas
