Simulation of EM emissions from printed circuit board traces

Recently electromagnetic interference (EMI) and electromagnetic emissions (EME) become a serious problem because of the high mounting density on printed circuit boards (PCBs) and the fast speed of ICs. Digital pagers, wireless input devices, hand-held radios, personal computers, and cellular phones and other devices have all become more prevalent in civilian and military environments. In today's market place, controlling emissions from these and other products has become a necessity to satisfy many standards and regulations. In addition, many of these products should fit into a larger community of electronic systems without interference among devices. EMI and EME problems can be taken into account at the design stage to reduce the overall cost of correcting such problems late in the development process.
