Researchers at King’s College London in the U.K. have successfully demonstrated control over the direction of movement of electromagnetic waves in waveguides through the use of circular polarization to send waves in a single direction along a metal surface. Their achievement marks the first time unidirectional waves were controlled with these methods and could have strong … [Read more...]

Scientists Demonstrate Storage and Release of Electromagnetic Waves in Metamaterial
While scientists have known since the 1990s that electromagnetic waves could be trapped and used for important applications like information storage and quantum optics, the complexity of the experimental setup and the inability to develop a method for releasing the waves in their original state has stalled significant research and development for almost two … [Read more...]
Lab to Study Effects of EMF on Oceans and Rivers
The Pacific Northwest National Laboratory in Richland is getting more than $6.8 million to study energy production from oceans and rivers. Lab researchers will lead a project to study how fish and marine mammals are affected by noise, electromagnetic fields and blade strikes from water power devices.LEARN MORE … [Read more...]
Distributed Decoupling Capacitor Effectiveness
The effect of connection inductance and ESL can limit the effectiveness of decoupling capacitors. Bruce Archambeault, Ph.D., IBM Research, Triangle Park, North Carolina, USA INTRODUCTION Decoupling capacitors serve two purposes. One is to provide charge to the ICs for functionality, and the second is to maintain a low impedance between power and ground-reference planes in … [Read more...]
ISO/IEC 17025 – Should the International Standard on Laboratories be Divided into Two Separate Standards?
Is there a need for a distinct testing lab standard and calibration lab standard? Daniel D. Hoolihan, Hoolihan EMC Consulting, Lindstrom, MN The flag-ship laboratory quality standard in the world is ISO/IEC 17025–General Requirements for the Competence of Testing and Calibration Laboratories. Based on years of experience using the standard, the author is recommending that … [Read more...]
