Interference Technology

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.

Read Part 1 of this CubeSats series here In 2016 and 2018, Bob Vermillion gave a series of groundbreaking presentations on “CubeSats Require ESD Handling Protocols for Launch & Space Survivability” to enthusiastic audiences of university graduate students, aerospace engineers, NASA civil servants and academic researchers at the NASA-Auburn Academy of Aerospace Quality Workshop, Huntsville, Alabama and NASA Quality Leadership Forum, Cape Canaveral.

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 produced at scale, it’s critical for RF/Microwave Engineers to understand how to characterize and test them accurately and efficiently.

Introduction The number of connected devices keeps growing every year. Millions of devices exchange data wirelessly to make our lives easier. Wireless connectivity simplifies installation by removing cables, but it uses the electromagnetic spectrum, which is becoming more and more crowded. User demands have shifted connectivity from being a convenience or a cost-reducing feature to a must-have one. Users do not want to replace the functionality of a smartphone with a wired connection.

FOR IMMEDIATE RELEASE Ayer, Massachusetts — April 22nd, 2026— Creative Materials, Inc. announces it has recently achieved International Traffic in Arms Regulations (ITAR) certification and successfully completed ISO 9001 and ISO 14001 recertification audits, strengthening the company’s ability to support customers operating in highly regulated, mission-critical aerospace, defense, and medical device industries. ITAR certification confirms that Creative Materials, Inc.

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 hitting RF applications that are reliant on plane-wave-based models.

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 apply mitigations to their product after the formal test fails, not knowing precisely what fixes to apply.

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 best power supply for harsh aerospace environments?

Signal has announced the introduction of its SHFWT Series Helical Wound Flat Wire Toroidal Inductors, broadening the Signal portfolio with a high-performance solution for demanding electronic designs. The SHFWT Series strengthens Signal’s lineup of chokes, coils, and inductors, responding to increasing demand for efficient, low-loss, high-frequency power components. The low profile SHFWT Series uses an edge-wound flat copper wire construction that allows more turns in a single winding layer.

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 testing. This raises an important question: Are conducted emissions easy to pass?
