Demystifying the Math of EMC
As we progress through the fold of technological developments, be it in commercial products, military advancements, automotive electronics, or any of the other industries where electromagnetic devices are developed, EMI will be present and EMC testing will be required. For those technical personnel who are walking into a laboratory for the first time, learning EMC because … [Read more...]
NEMA Receptacles 5-20R with Ease of Assembly and More Power Performance
SCHURTER introduces the new NR520 series NEMA 5-20R outlets, adding to its existing range of 5-15R types. The new configuration extends the range of outlets rated 15 A to include a 20 A version for applications with increased power demands. SCHURTER’s NR520, which is the NEMA standard 5-20R [20 A at 125 V] configuration, complements SCHURTER’s existing range of outlets with … [Read more...]
EMC and EMI Simulation for Launchers and Satellites
By: Yannis Braux and Stephen Murray CST Computer Simulation Technology Introduction EMC and EMI analysis plays an important role in ensuring the correct functioning of electronic systems and guaranteeing reliability throughout their lifetimes. This task is all the more difficult and crucial when the system is complex or exists in a challenging EM environment. This … [Read more...]
A Circuit Theory Approach to Calculating the Attenuation of Shielding Barriers
Abstract There are two commonly used methods for approximating the attenuation of shielding barriers. This approximation is defined as shielding effectiveness (SE) for shielding materials used in the design of shielded enclosures. Both methods use wave theory and quasi-stationary assumptions. One of the methods uses Maxwell’s equations to estimate the shielding, and the other … [Read more...]
How to Choose Particle-Filled Silicones to Meet Multiple Design Requirements
Many electronic designs need shielding materials that combine resistance to electromagnetic interference (EMI) with other application-specific requirements. For example, the EMI gaskets that are used in military touchscreens need to attenuate EMI emissions, provide electrical conductivity, and ensure environmental sealing. These shielding gaskets also must also cushion the unit … [Read more...]
The Future of Shielding
THE FUTURE OF SHIELDING The future is not all that far off. With more electronic devices that are getting smaller, more portable and with continuing faster speeds, EMI or RF issues will continue to increase. There will be more integrated system-onchips (SoCs) where several functions will all be in one device that will need to be electromagnetically isolated. As an example, a … [Read more...]
Introduction to MIL-STD-461G
Where MIL-STD-464C serves as a system/platform level set of requirements, MIL-STD-461G serves as an equipment/subsystem level set of requirements. Similar to MIL-STD-464C, MIL-STD-461G was developed as an “Interface Standard” to allow usage without a waiver. The overall structure of the two documents is also the same in that both have a contractual main body and a very … [Read more...]
Spectrum Management and the EME
Certification In years past, E3 (Electromagnetic Environment Effects) control and Spectrum Supportability were considered separate entities and design and development efforts were often segregated. Over the last several years, the trend has shifted to a more consolidated approach and today the two areas go hand in hand. Spectrum Supportability starts with equipment spectrum … [Read more...]
Introduction to MIL-STD-464C
Responding to increasing criticism, Secretary of Defense William Perry issued a memorandum in 1994 that effectively eliminated the use of most defense standards. This has become known as the “Perry memo”. Many defense standards were canceled. In their place, the DOD encouraged the use of industry standards for quality assurance. MIL-STD-464 was developed as an “Interface … [Read more...]
