Book Review:

Title: Electromagnetic Compatibility-principles and applications
Second Edition, revised and expanded.

Author: David. A. Weston
Publisher: Marcel Dekker, Inc. 2001, ISBN 0-8247-8889-3


This second edition of “Electromagnetic Compatibility” book by D.A. Weston extends over 840 pages, contains 12 chapters and 5 appendixes, and includes over 900 equations, photos, figures and tables, 500 more than in the first edition.

The new information in this second edition refers to: computer modeling programs, additional commercial and military EMI test methods, a chapter on PCB layout, new data on cable radiation and coupling to cables, extending out to 12GHz, and on EMI enclosure shielding.

Electromagnetic interference (EMI) means radiation or reception of high frequency signals by electric contact or (and) electromagnetic waves radiation by an electric equipment which is capable to detune, derate, disturb the proper functioning of that or other electric equipment in its proximity, in general.

Electromagnetic compatibility could be defined as the engineering art by which EMI is reduced to acceptable levels inscribed in pertinent standards.

As all electric and electronic equipment may be a source of EMI, the subject of the book is fairly general.

The book is written for the design engineer, technologist, technician, and engineering manager who designs, fabricates, maintains or specifies equipment to meet EMC standards or to function safely in a given electromagnetic environment.

The practical approach of the book is evident. The number of equations is kept to a minimum and most of the theory is validated by measurements. Numerical examples though representative case studies abound in the book.

EMI diagnostic measurements and pertinent equipments that comply with most recent EMC standards are described.

In general, the book reflects the author’s ample experience gained in EMC consulting and over a 12 year period of seminars on same subject.

The book is extremely clear, concrete and comprehensive in explaining various phenomena and solutions for EMC.

Chapter 1 introduces EMI and the magnetic environment, while Chapter 2 rounds up the introduction with: E and H, Near and Far Fields, Radiators, Receptors and Antennas.

Typical sources and the characteristics of their radiated and conducted emissions are presented in Chapter 3 while Chapter 4 deals with crosstalk, electromagnetic coupling between PCB tracks, wires and cables.

Chapter 5 details components, emission reduction techniques, and “noise immunity and Chapter 6 treats electromagnetic shielding in considerable depth.

Cable shielding, coupling from E and H fields and cable emissions are Presented in Chapter 7 and grounding and bonding in Chapter 8.

EMI measurements, control requirements and test methods (Chapter 9), systems EMC and Antenna coupling (Chapter 10), printed circuit boards (Chapter 11), and EMI&EMC control, case studies, EMC prediction techniques and computational electromagnetic modeling (Chapter 12) complete the rich content of this well conceived and well written book on EMC.

We warmly recommend David A. Weston’s book on EMC to all interested in the subject, from Academia and students to electric & electronic equipment management, design, fabrication and maintenance engineers.
