Fundamentals of EMC Design: Our Products Are Trying To Help Us

 

INTRODUCTION We often design electronic products only to find that when we test them for electromagnetic compatibility (EMC), their emissions and/or immunity are not as good as we need them to be. Usually, at this time, we feel as if we are fighting against the laws of physics to contain the conducted and radiated emissions, or to reduce susceptibility. But in fact the laws of … [Read more...]

Petite Particle Accelerator Proton Gun Kills Tumors

 

Scientists at the Compact Particle Acceleration Corporation are developing a 13-foot-long particle accelerator that costs about $30 million. Most accelerators use large magnets to generate the electromagnetic field that pushes charged particles. The magnets require 10-foot-thick concrete shielding and bulky hardware. CPAC's prototype creates the electromagnetic field with … [Read more...]

Simple Method for Predicting a Cable Shielding Factor, Based on Transfer Impedance

 

For a shielded cable, an approximate relationship valid from few kHz up to the first cable resonance can be derived from its Transfer Impedance (Zt) allowing to predict the cable shielding factor. This Cable Shielding factor, as a figure of merit, is often preferred by engineers dealing with product specifications and early design. Being not necessarily EMC specialists, they … [Read more...]

Global EMC Shielding Market Expected to Grow

 

According to new research, the switch from wired to wireless technology and the “emergence of a number of directive and regulations in favor of EMC shielding solutions drive the EMC shielding market.” Alternatively, the smaller scale of devices coupled with their complexity and high cost is said to slow the growth of the market. For revenue generation, Asia has the highest … [Read more...]
