The 2003 Columbia re-entry accident was caused by a piece of liberated external tank foam that struck and damaged the left leading edge during powered ascent. Computational and experimental electromagnetics were ultimately applied to foster the development of a new NASA Ascent Debris Radar (NDR) for the remaining 22 Shuttle missions. In the process, countless static and dynamic radar signature and EMI/EMC calculations and tests were completed to assure this safety-critical radar system was ready for the return to flight (RTF) missions.
Traditionally, the start of a new year is a time when we reflect on the progress we’ve made during the year passed and set our goals for the new year. We’ve queried training resources in our industry to provide you with an overview of free or affordable solutions to meet your training goals in 2022.
For engineers new to the field of EMC, the road can look very steep indeed. But, with a plan (and some work!), you can grow from EMC novice to EMC expert.
This article presents the fundamentals and application of capacitors. What is a capacitor, and how do we select them? Techniques of selecting capacitors and things to consider when using capacitors are highlighted. Both practical examples and simulation are used to demonstrate the key points.
Heat flow analysis for semiconductor ESD situations can be approximated to one dimension, and then captured with a generalized Ohm’s Law using a complex impedance. Methods can include time-dependent electrothermal pulses and feedback due to self-heating, with solutions readily carried out on any desktop computer.
The shielding performance of bayonet vs. threaded connectors is measured and some possibly surprising conclusions are drawn. Bayonet connectors – more useful than you might think.
This article describes three troubleshooting methodologies doctors use to diagnose (troubleshoot) medical problems. These same techniques have proven useful in my own EMC consulting practice.
End-product manufacturers can help protect against supply chain disruptions that impact the availability of listed or recognized components by proactively identifying suppliers who can provide substitute components that conform with their listing requirements.
Sometimes we can get stuck in our careers, doing the same things over and over again, day in and day out. One way we can break free from this situation and improve our cognitive abilities is to continue to study and learn new things – even subjects outside of what might be considered our chosen specialty.
Our knowledge of ESD and how to control it has grown significantly over the past 50 years. This article maps the history of that journey.
