Most of us consider a number of factors, exoteric and esoteric, while designing [or selecting] our homes and in the configuration of the numerous modern technological devices and domestic appliances, most of them electrical and electronic, therein. Recently I saw a programme on TV where a Vastu Shastra expert was advising viewers not only regarding the various aspects of designing and building living environments that are in harmony with the physical and metaphysical forces but also specifying optimal locations and layouts for various electrical and electronic appliances and devices in both residential homes and workplaces. I listened with intriguing interest as he gave precise directions and specified exact locations for positioning of Televisions, Computers, Communication Devices, Microwave Ovens, Music systems and other appliances, and fascinated by the congruence between principles and aspects of Vastu and Electromagnetic Compatibility [EMC] and wondered whether the expert in reality was actually an EMC Design Engineer in addition to being a Vastu Shastra Specialist.


When you design or select or configure your house or office I am sure you consider various aesthetic, architectural, financial, utilitarian, geographical, interior and exterior design and other practical aspects, maybe even incorporate the principles of Vastu Shastra and Feng Shui, but do you give even a fleeting thought to EMC? In today’s world with the increasing use of electricity and electronic technology we are under continual exposure to Electromagnetic Field [EMFs], both inside and outside our homes and workplaces, radiating from radiating from electricity power lines, household wiring, microwave ovens, computers, monitors, televisions, communication devices, cellular phones, electric and electronic appliances and “Electropollution” is an increasingly serious form of Environment Pollution and merits serious consideration. Apart from hazards to our health, Electromagnetic Interference [EMI] is detrimental to the proper functioning of most electrical, electronic, IT, ITES, communication and technology-based systems and may cause malfunctions and even potentially disastrous and fatal accidents.


The book being reviewed – EMC for Product Designers by Tim Williams – is one of the most comprehensive reference books I have read on the subject. Comprising sixteen chapters arranged in three parts [Legislation and Standards, Testing and Design] the author lucidly covers most micro and macro aspects of EMC Management in meticulous detail. The logical sequence of topics, clear diagrams, tables and illustrations facilitate easy understanding of this complicated subject. The Design Checklist, interesting Case Studies and useful mathematical formulae in the appendices and the extensive bibliography add value to the reference book.


Whilst the earlier chapters provide an excellent understanding of the EMC Standards and the basic theoretical principles of EMI / EMC, the “meat” of the book lies in the chapters on Systems EMC and EMC Management which encapsulate all relevant facets of EMC in a holistic manner. I wish the author had included a detailed chapter on Electromagnetic Health Hazards and mitigation techniques. This vital topic concerning all of us humans seems to have not been accorded the due importance it deserves and I hope the author includes a comprehensive chapter on pertinent aspects in the next edition.


I commend this book – it is an excellent reference book for designers, students, practising professionals in the field and a useful addition for all engineering and technical libraries.
