Introduction Missile platforms operate in some of the most extreme electromagnetic (EM) environments encountered by aerospace systems. The combination of high‑power radar, directed‑energy weapons, lightning, electromagnetic pulse (EMP), and electro‑static discharge (ESD) creates a complex threat landscape that can compromise functionality, safety, and survivability. Emphasis … [Read more...]
What’s New in MIL-STD-461H
The long-awaited revision to MIL-STD-461H was released on April 17, 2026. This revision formally supersedes MIL-STD-461G, issued on December 11, 2015. However, anyone involved in the MIL-STD-461 compliance arena understands that adoption through the procurement cycle will take time. There is no reason to discard those copies of revisions A through G anytime soon. Although I … [Read more...]

Evaluating Patch Antenna Printed Circuit Boards Utilizing RF Absorber and S11 Measurements
Introduction Patch antenna printed circuit boards (PCBs) are among the most common pieces of radio frequency (RF) hardware that exist in modern systems today. Wireless communications, automotive radar, and aerospace/defense systems rely heavily on these structures for transmitting and receiving electromagnetic energy. Since these structures are … [Read more...]
Why Maxwell’s Plane Wave Solution Matters in RF
Transmission lines, antennas, and RF measurement systems all rely on a single electromagnetic model - the plane wave solution to Maxwell’s equations. While often treated as a theoretical result, this solution governs how energy propagates, reflects, radiates, and ultimately contributes to interference in real RF hardware. There are several, heavy … [Read more...]
Your First EMC Bench Setup
Complying with EMC regulations seems to be a challenge for many companies who manufacture electronic products. This usually comes to a head, if considered near the end of the development cycle. As an EMC consultant helping hundreds of clients, I've witnessed the resulting cost and schedule delays. Invariably, engineers will attempt to troubleshoot and … [Read more...]
Compliant by Design: Where Precision Meets Power Integrity in Aerospace Applications
Power integrity and regulatory compliance are the technical foundation of any mission-critical system. When they fail, the consequences can risk safety and costly assets, which is why design must produce predictable electrical behavior and a clear, testable path to certification. This brings focus to a key question for program managers: what is the … [Read more...]
Understanding Common-Mode Current Paths in Conducted Emissions
Conducted emissions failures, across commercial, industrial, automotive, and defense sectors, remain consistently ranked among the top three most common EMC test failures. This is somewhat surprising, given that filtering techniques are well understood and widely used by design engineers. Yet, many products continue to struggle during conducted emissions … [Read more...]
