As electromagnetic environments grow more complex, RADHAZ assessments have become critical for military safety. Radio frequency radiation can ignite fuel, trigger explosives, and harm personnel. This article explores the three primary hazard areas—HERP, HERO, and HERF—examining how assessments protect against dangers from both high-power radars and low-power transmitters in modern military operations.

With the increase in online transactions, use of social media, and digital connectivity, ensuring the safety and well-being of minors has become a high priority for parents, digital service providers, policy makers, and regulators across the globe. The advancement of age-appropriate design and age verification standards by the IEEE Standards Association (IEEE SA) is helping stakeholders, including digital services providers, policy makers, and regulators, to address requirements from various jurisdictions around the world. 

Warnings and instructions are a necessary part of any safe product. Rarely is a design so safe that there are no warnings and instructions that need to be followed. On the other hand, failure to follow warnings and instructions can turn an otherwise safe product into one that is hazardous. Is it foreseeable that users will not read or follow this information? And if so, what effect does that have on the manufacturer’s potential legal liability for injuries suffered while using this product?

Shielding effectiveness changes dramatically in the near field. This month's column introduces wave impedance concepts for electric and magnetic dipoles, revealing why electric sources behave as high-impedance radiators while magnetic sources act as low-impedance radiators—distinctions critical for designing effective shields close to emission sources.

High-speed automotive serial links supporting ADAS features face a critical challenge: meeting stringent system-level ESD requirements while maintaining signal integrity at 10+ Gbps. This column presents an innovative on-chip protection architecture embedding ESD clamps within T-coil circuits, achieving 8kV ISO protection while supporting data rates exceeding 36 Gbps.Retry
