Zapped: why your cell phone shouldn't be your alarm clock and 1,268 ways to outsmart the hazards of electronic pollution

Gittleman, Ann Louise
"In the last 15 years alone, technology has expanded into every aspect of our lives. Today 84 percent of Americans own a cell phone, 89 million of us watch TV beamed to us by satellite, and you can't have a cup of coffee at Starbucks without being exposed to WI-FI. We are constantly being exposed to electromagnetic fields (EMFs), invisible lines of force that surround all electrical devices, and at a rate 100 million times greater than our grandparents were. We're being zapped--high levels of electromagnetic fields and the wavelengths and frequencies they produce have reached the point of toxicity, making us tired, irritable, and weak. Gittleman's groundbreaking book provides a proactive approach that counteracts the toxic effects from an almost constant bombardment of energy fields. This simple and effective program is based on the latest research, case studies, and years of clinical practice. In Zapped readers will learn the science behind digital allergies, and how to determine their level of sensitivity and measure the strength and location of harmful electromagnetic fields in your home and office. With step-by-step instruction the author walks you room-by-room, teaching you how to remake the force fields in your environment and create positive energy flow. Gittleman provides practical solutions to protect you and your family, providing a happy and healthy life coexisting with technology"--

Advances in computational electrodynamics: the finite-difference time-domain method

Taflove, Allen
Updates the 1995 text on the same topic. The 12 contributions cover high-order methods, multiresolution expansion, explicit time-domain solutions of Maxwell's equations via generalized grids, analysis of periodic structures, modeling of antennas, high- speed electronic circuits with active and nonlinear components, physics-based modeling of millimeter-wave devices, and microcavity resonators. The book is intended as a single-source reference on the state of FDTD art for university graduate students and faculty and professional engineers and scientists involved in electromagnetic technology. Appends a list of acronym expansions. Annotation c. by Book News, Inc., Portland, Or.
