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 solutions to EMI/EMC problems, and in the execution of major programs that require verification to electromagnetic environmental effects.
