The PCB Design Quiz: Seven Questions to Sharpen Your Skills

In high‑speed digital and power electronics, small design choices can have a major impact on signal integrity (SI), electromagnetic interference (EMI) performance, and overall system reliability. From understanding how signals propagate to optimizing capacitor placement, stackups, connector pinouts, and grounding strategies, each detail shapes the behavior of circuits in subtle but important ways. In this […]

Eight Steps to Building a Defensible E3 Simulation Analysis Plan

Electromagnetic environmental effects (E3) have long been a core part of aircraft certification, but today’s rapidly evolving aerospace landscape has amplified both the complexity and the importance of getting E3 right. As aircraft become more electrified and more tightly integrated, understanding how electromagnetic environments affect both the platform and its system is becoming increasingly challenging. […]

Preventing Signal Failures as High-Power Data Centers Reshape Transmission Networks

Artificial intelligence (AI), cloud computing, and high-performance computing are driving unprecedented demand for data center infrastructure. Developers often build these facilities near existing transmission and rail corridors to accelerate construction. But while this proximity offers speed and convenience, it also creates new electromagnetic challenges for utilities and railroads. Electromagnetic interference (EMI) and electromagnetic compatibility (EMC) […]

System-Level EMC Simulation Using SIwave, HFSS, and Ansys EMC Plus

Electromagnetic compatibility (EMC) challenges are becoming increasingly complex as modern electronics evolve into tightly integrated systems. Products across aerospace, automotive, and consumer electronics combine high-speed digital circuits, radio frequency (RF) components, dense printed circuit boards (PCBs), and extensive cable harnesses within compact enclosures. Accurately predicting EMC performance requires multi-domain analysis rather than isolated modeling. “EMC […]

The Lunar Dust Challenge: How Simulation + Testing Strengthen Spacesuit Reliability

As NASA’s Artemis program prepares to return humans to the Moon, engineers are shifting their focus from landing safely to performing sustained lunar surface operations. Teams are designing a new generation of Artemis lunar spacesuits to improve mobility, resist constant exposure to jagged lunar regolith, and support increasingly sophisticated electronics and life-support systems for extended […]
