The team at Georgia tech has created a Rotman lens-based rectifying antenna, or rectenna, system. This flexible rectenna system has the capacity to harvest millimeter-waves within the 28-GHz band.
TDK Corporation offers a new series of current-compensated EPSOC double-ring core chokes for the suppression of common-mode interferences in switch-mode power supplies, converters, and domestic appliances.
Element Materials Technology has expanded its product qualification testing (PQT) capabilities at its testing sites in Hull and Hitchin (UK) to address the broader range of wireless technology requirements.
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.
Grounding is often viewed from separate points of view - safety, ESD, or EMI. This article combines all these aspects together so that practitioners can address grounding at the factories and in the laboratories in a comprehensive way.
Secure facility designs often comingle ICS/ICD-705 and NSA 94-106 design requirements, creating project confusion with significant design and cost implications. This article focuses on bringing some clarity to the differences between ICS/ICD-705 design guidance and NSA 94-106 performance requirements. The related secure facility design and construction process is also reviewed.
This article presents the EMC design techniques for electric vehicle powertrain modules. High voltage EMC regulations for powertrain modules are reviewed first to help understand associated design challenges. The design techniques are then demonstrated in detail to help engineers design a module that will pass the EMC requirements in the test chamber.
The electronic industry has embraced simulation to address several complex design challenges, but reliability is still mostly dealt with best design practices and tested with prototypes. In this article, we present how modeling and simulation approaches can help designers perform virtual prototyping and uncover reliability issues especially EOS/ESD before going for physical prototypes.
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.
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.
The way you market your product can turn an otherwise safely designed product into an unsafe product that causes injury and creates liability for the manufacturer and product seller.
This article discusses the IEC 60601 Amendments Project, for Medical Electrical Safety, some of the changes to the General and Collateral Standards of the Project, and their impact on manufacturers. The future of the 60601 series of standards is also discussed.
