Electric vehicles introduce complex EMC challenges as high-switching inverters and E-drives create electromagnetic interference affecting safety-critical ADAS systems. Traditional static testing at constant speeds is insufficient—dynamic EMC testing under realistic driving conditions is essential to properly characterize emissions and ensure compliance.

Discover why copper shields outperform steel at low frequencies but steel dominates at high frequencies. This practical guide presents simplified formulas for calculating electromagnetic shielding effectiveness, revealing the surprising crossover point at 4200 Hz where material performance flips.

EMI filters are essential electronic components that eliminate unwanted electromagnetic interference, ensuring devices operate reliably without disrupting nearby equipment. From low-pass to common-mode chokes, these filters reduce emissions, enhance immunity, and ensure regulatory compliance. Proper design requires identifying noise sources, selecting quality components, and strategic placement for optimal electromagnetic compatibility.

Can you use everyday electronics on an aircraft, or do they need special military-grade testing? Patrick Andre examines when commercial off-the-shelf equipment works fine versus when it could fail catastrophically in demanding environments like military aircraft and helicopters.

The IEEE EMC Society is advancing three shielding effectiveness standards: one for large enclosures, another for smaller boxes, and a new standard for portable device pouches. Measuring electromagnetic shielding in space-constrained environments presents significant technical challenges that require innovative solutions.

Don MacArthur explores essential EMC test chambers—from anechoic to reverberation types—used across industries like automotive, aerospace, and consumer electronics. Learn key design considerations including material selection, shielding effectiveness, and applications ensuring electromagnetic compatibility compliance.

Field failures traced to ESD-induced USB hub damage in deployed POS terminals. Through systematic H-field probe analysis, we identified poor connector-to-chassis bonding as the root cause—a preventable design oversight with expensive retrofit implications.

Naval ships have lots of powerful radars and radios that create electromagnetic interference. Scientists studied how this interference leaks into protected rooms through wire holes, discovering new mathematical patterns that help predict when sensitive equipment might be damaged by electromagnetic waves.
