Tim McDonald, PhD is the President and Co-Owner of Electro Magnetic Applications where he has implemented new system-modeling approaches to simulate the interaction of systems and their electronics with electromagnetic environments in a shorter time, with more accuracy, and at a lower cost. He is a consultant to NASA and DoD major primes for specialty engineering of critical systems, development of novel nanomaterial solutions to EMI/EMC problems, and in the execution of major programs that require verification to electromagnetic environmental effects.
Select consulting engagements:
• Lightning and spacecraft plasma charging analysis of Lockheed Martin NASA Orion MPCV
• Lightning and HEMP analysis of Orbital Sciences MDA Ground-based Midcourse Defense Booster Vehicle rocket
• Program manager, analyst, and onsite coordination for Bell Helicopter lightning/HIRF certification support
• Program manager, analyst, and onsite coordination for Scaled Composites lightning mitigation
He has done training on modern numerical simulation-aided design to update the capabilities of Electromagnetic Effects departments at aerospace companies around the world including:
• Lockheed Martin
• Turkish Aerospace Industries
• Bell Helicopter
• Fuji Heavy Industries (Subaru)
In addition, he has specific experience in helping develop new nanomaterial solutions to E3 applications, including novel lightning protection approaches and transparent conductors.
