This article introduces a concept of a phasor which is extensively used in several EMC topics including electromagnetic waves, antennas, and transmission lines.

Most EMI issues are caused by a resonance that is excited somewhere in the system. It may be a resonance of a cable acting as an antenna or a heatsink energized by the power electronics switches bolted to it, becoming a good radiator. In this article, we look at the indicators that signal the presence of structural resonances and provide techniques for fixing the EMI issues. Practical case studies are presented to demonstrate the techniques.

Ethernet solutions have been popular in industrial and computing applications for several decades but were not widely adopted in the automotive area. Automotive ethernet enables fast and robust data communication, with high flexibility in bus topologies for multiple electronic control units (ECUs).

When Gaston Planté invented the rechargeable battery in 1859, a new system of stored energy emerged. Today, digital technology has helped to make the electrochemical battery smart by providing a window into a battery’s state-of-function.

This article addresses China’s latest requirements, including technical details, for 2.4 GHz and 5 GHz equipment.

Reliability issues need to be continuously addressed during technology development as technologies further advance into novel transistor structures such as FinFETs and Multi-gate devices.

It has been reported widely in the Japanese press that electromagnetic interference caused by illegally modified transceivers on trucks is suspected of causing two accidents by disabling the braking system of commuter buses.

As a compliance engineering professional, you may encounter situations when you must consider how multiple and often conflicting requirements apply to your product and how to deal with them effectively.
