I have 40 years of experience, and specialize in the field of electro-magnetic interference with specific knowledge in the areas of controlling emissions and susceptibility. I have published on such topics as grounding and bypass capacitor routing. I was retained by a large multinational corporation to get the emissions into compliance for a product that they had had 7 to 9 engineers working on the problem for over 7 months without success. I told them that I could solve the problem in one week. I did so in exactly 7 days.
