EMI / EMC in Military Systems
Description
Systems EMC (Electromagnetic Compatibility) involves the control of EMI (Electromagnetic Interference) at the systems, facility, and platform levels (e.g. outside the box.) This three-day course provides a comprehensive treatment of EMI/EMC problems in military systems. These include both the box level requirements of MIL-STD-461 and the systems level requirements of MIL-STD-464. The emphasis is on prevention through good EMI/EMC design techniques – grounding, shielding, cable management, and power interface design. As we go through MIL-STD-464 and 461, at each step we’ll explain the fundamental principles behind the requirements. Hardware demonstrations will help students understand how some of the strange behaviors associated with EMC play out in the real world. Each student will receive a complete set of lecture notes.
Thinking about EMC training? The payback is there — just one extra trip to the test lab can cost you $10-20K in test and engineering time! Not to mention the additional cost of being late to market, or the cost of fixing EMI problems in the field.
Instructor(s):
Karen Burnham has worked in and around the aerospace, defense, automotive, and broader consulting world since 1996. She has a BS in Physics, an MS in Electrical Engineering, and a talent for translating EMC to English. She has managed requirements and test planning for NASA and the Dream Chaser spaceship and others. She has been a MIL-STD-461 test director for avionics units. She has done troubleshooting on electric vehicles for Ford Motor Company and others. She has initiated innovative SBIRs and STTRs through government centers and worked on classified programs. She has consulted on projects across a wide swath of industries and sits on multiple international standards committees, landing her in her current role of Vice President of Standards for the IEEE EMC Society.
Ms. Burnham founded EMC United, Inc. in 2024 to focus on helping companies and hardware designers solve EMC problems, ideally before they even start. She believes that, far from being black magic, EMC can be understandable (and even fun!), and she hopes to spread that passion more widely.
