Design

The evolution of E and H fields on aircraft struck by lightning is a complex process. An October 2014 in-flight lightning strike is reviewed in this article as an example that inspires a fresh look at how lightning E and H fields should be considered for indirect effects certification.

Low-cost designs are often an underserved and challenging part of a layout engineer’s career and getting increasingly complicated.

It is a common misconception that any product that complies with IEC 60950-1 will also comply with IEC 62368-1. A key goal of this article is to help readers of IEC 62368-1 understand the underlying safety concerns that the new requirements are trying to address.

Why the effects of nearby lightning might be over-estimated, or in some cases underestimated, and how to get more realistic estimates.

Scientists have designed and created the longest-lasting high-performance organic flow battery in history.

Understanding skin effect and surface currents saves us a lot of time and cost in the design of our product’s shielding and filtering, especially for tough EMC standards such as automotive, military or aerospace.

Scientists from Northwestern University have found a new way to stabilize lithium-ion batteries with record-high charge capacities.

A whole new world of commercially available battery-free 'smart toys' could be coming to a store near you -- and sooner than you think.

Researchers have discovered that a tiny pinch of salt can significantly improve battery performance.

A new type of microchip could provide us with battery-free power for the future.
