The Electromagnetic Interference and EMC are one important phenomenon, since the EMI
causes degradation in the performance of electric and electronic instruments.
The EMI- problem may decrease effectiveness of sensitive devices and even may lead to
a
failure of its operation.
This paper studies EMI-problem between different systems by using convenient computer
programs as CST, which provides modulation and simulation of this problem. This method provide
ability to trace and evaluate EMI microscopically in space and real time.
