EMF How-To Guides

In this book, internationally respected EMF measurement expert Hubert Trzaska discusses the specific problems of EMF measurements in the often confusing near field and the main factors limiting measurement accuracy. Book describes methods that provide accurate data to aid the development of new, improved standards. Measuring methods are examined for electric fields and magnetic fields; measurement discussions include power density and photonic EMF measurements. 232 pages, 2001

Laboratory studies of electromagnetic (EM) signal propagation through construction materials were carried out as part of the NIST initiative. In this report, power attenuation aspects are discussed. The materials investigated included brick, masonry block, eight different concrete mixes, glass, plywood, lumber (spruce-pine-fir), drywall, reinforced concrete, steel reinforcing bar grids, variations of the plywood and lumber tests in which the specimens were soaked with water, and composite specimens involving brick-faced masonry block and brick-faced concrete. For each material, varying thickness specimens were fabricated in order to measure attenuation as a function of penetration distance. Measurements of power loss were taken at 2 MHz intervals from 0.5 to 2 GHz and from 3 to 8 GHz. Frequency power spectra were discretely generated for each material as a function of thickness. Excellent tables and graphical data. Extremely useful for predicting the shielding effectiveness of common building materials. 200 pages, 1997.

As the name implies, this is a "how-to" treatise on the various methods to reduce electric, magnetic and radiofrequency fields. Has a great beginning which explains the scientific basics of electric and magnetic fields (some of the best descriptions of terms such as permeability, ground plane, ferrites, and hysteresis that we have seen). Includes whole chapters on electric shielding, magnetic shielding, shielding in circuits, considerations for isolation transformers and utility power, and high frequency shielding. Some math is inevitable so this is not for beginners, but this book focuses more on how to design the circuit or fabricate the shield to achieve results. 1998 200 pages.

A charming and useful book explains how to cook and store food, pump water, wash clothes and even run farms and business- all without electricity. Want to know how to light a room? Keep warm? Communicate without a phone? Find some obvious and not so obvious answers to these and many more questions. Based on the non-electric and practical lifestyles of the Amish. 128 pp. 1990

Many people want to know how EMF readings in their home compare to fields found in other homes or workplaces. Knowing this may help you decide if your situation is unusual. Making measurements may help you develop some simple strategies to avoid some fields. Discusses what fields are, where they come from, comparisons of findings in various home and workplace settings, and a little about what is know about health risks. Useful reading for any gaussmeter user, but biased toward the idea that EMFs are not a problem. 1992

A book to help you chose and properly install the correct antenna to pull signals out of the air. The Right Antenna provides easy-to-understand information on a wide variety of antennas. It explains how antennas work and breaks them into TV and FM for discussion. A separate chapter is devoted to interference, and antennas used by hams for antenna band operation. The basic concepts of cellular telephone system operation are explained and the most popular antennas are discussed. Also includes chapters on DSS, satellite and TV amplifier antennas. A great how to book on selecting and installing antennas for entertainment and communication devices. Reg price: $24.95
