This book deals with the two fundamental subjects of electromagnetism. It is a useful text for courses in electromagnetism, electrical circuits, mathematical methods of physics, and the history and philosophy of science. It covers how to calculate force between two current carrying circuits, and net force on a part of a closed circuit. The calculation of the mutual inductance between two circuits and self-inductance of a single closed circuit is also described. Experiments explain the main expressions of Ampere and Grassmann. A must to help deepen the knowledge of the mind of any student of science.

Biomedical implants used as neural prostheses are often powered by low frequency wireless inductive systems. Such an inductive coil system consists of the primary coil outside the body and the secondary coil implanted on-chip with the prosthesis. This thesis proposes novel designs for the geometry of the on-chip coil and computes the inductive coupling obtained by using the proposed geometries. Traditional inductance calculation methods involve the use of computationally expensive field solvers or complicated analytical methods. A computational method employing the partial inductance concept is used to calculate the self and mutual inductances at low frequencies of certain regular 2-D and 3-D geometries (spirals, rectangular helices, pyramidal inductors etc.). These inductor geometries are fabricated and the measurement results match closely with the values predicted by the simulations. This provides an analytically simple, cost-efficient and computationally fast method of finding the self and mutual inductances of regular 2-D and 3-D geometries which can be used to reliably compute the coupling of the proposed on-chip inductor geometries. The inductor geometry for optimal power transfer can be chosen on the basis of these inductance calculations.

The only resource devoted Solely to Inductance Inductance is an unprecedented text, thoroughlydiscussing "loop" inductance as well as the increasingly important"partial" inductance. These concepts and their proper calculationare crucial in designing modern high-speed digital systems.World-renowned leader in electromagnetics Clayton Paul provides theknowledge and tools necessary to understand and calculateinductance. Unlike other texts, Inductance provides all the detailsabout the derivations of the inductances of various inductors, aswell as: Fills the need for practical knowledge of partial inductance,which is essential to the prediction of power rail collapse andground bounce problems in high-speed digital systems Provides a needed refresher on the topics of magnetic fields Addresses a missing link: the calculation of the values of thevarious physical constructions of inductors—both intentionalinductors and unintentional inductors—from basicelectromagnetic principles and laws Features the detailed derivation of the loop and partialinductances of numerous configurations of current-carryingconductors With the present and increasing emphasis on high-speed digitalsystems and high-frequency analog systems, it is imperative thatsystem designers develop an intimate understanding of the conceptsand methods in this book. Inductance is a much-neededtextbook designed for senior and graduate-level engineeringstudents, as well as a hands-on guide for working engineers andprofessionals engaged in the design of high-speed digital andhigh-frequency analog systems.

The modern wireless communication industry has put great demands on circuit designers for smaller, cheaper transceivers in the gigahertz frequency range. One tool which has assisted designers in satisfying these requirements is the use of on-chip inductiveelements (inductors and transformers) in silicon (Si) radio-frequency (RF) integrated circuits (ICs). These elements allow greatly improved levels of performance in Si monolithic low-noise amplifiers, power amplifiers, up-conversion and down-conversion mixers and local oscillators. Inductors can be used to improve the intermodulation distortion performance and noise figure of small-signal amplifiers and mixers. In addition, the gain of amplifier stages can be enhanced and the realization of low-cost on-chip local oscillators with good phase noise characteristics is made feasible. In order to reap these benefits, it is essential that the IC designer be able to predict and optimize the characteristics of on-chip inductiveelements. Accurate knowledge of inductance values, quality factor (Q) and the influence of ad- cent elements (on-chip proximity effects) and substrate losses is essential. In this book the analysis, modeling and application of on-chip inductive elements is considered. Using analyses based on Maxwells equations, an accurate and efficient technique is developed to model these elements over a wide frequency range. Energy loss to the conductive substrate is modeled through several mechanisms, including electrically induced displacement and conductive c- rents and by magnetically induced eddy currents. These techniques have been compiled in a user-friendly software tool ASITIC (Analysis and Simulation of Inductors and Transformers for Integrated Circuits).

Praise for Noise Reduction Techniques IN electronic systems "Henry Ott has literally 'written the book' on the subject of EMC. . . . He not only knows the subject, but has the rare ability to communicate that knowledge to others." —EE Times Electromagnetic Compatibility Engineering is a completely revised, expanded, and updated version of Henry Ott's popular book Noise Reduction Techniques in Electronic Systems. It reflects the most recent developments in the field of electromagnetic compatibility (EMC) and noise reduction¿and their practical applications to the design of analog and digital circuits in computer, home entertainment, medical, telecom, industrial process control, and automotive equipment, as well as military and aerospace systems. While maintaining and updating the core information—such as cabling, grounding, filtering, shielding, digital circuit grounding and layout, and ESD—that made the previous book such a wide success, this new book includes additional coverage of: Equipment/systems grounding Switching power supplies and variable-speed motor drives Digital circuit power distribution and decoupling PCB layout and stack-up Mixed-signal PCB layout RF and transient immunity Power line disturbances Precompliance EMC measurements New appendices on dipole antennae, the theory of partial inductance, and the ten most common EMC problems The concepts presented are applicable to analog and digital circuits operating from below audio frequencies to those in the GHz range. Throughout the book, an emphasis is placed on cost-effective EMC designs, with the amount and complexity of mathematics kept to the strictest minimum. Complemented with over 250 problems with answers, Electromagnetic Compatibility Engineering equips readers with the knowledge needed to design electronic equipment that is compatible with the electromagnetic environment and compliant with national and international EMC regulations. It is an essential resource for practicing engineers who face EMC and regulatory compliance issues and an ideal textbook for EE courses at the advanced undergraduate and graduate levels.
