Electromagnetic radiation is that are what the energy is composed of from the electricity energy and magnetism that space moves commonly,and this energy is produces by the electric charge migration.The computer is we live the essential friend ,However case's electromagnetism revelation actually frequently is threatening us ,This paper has simply simulated the CPU how to reveal the electromagnetic wave outward through the engine case row of wind eyelet. In this paper, the first wave equation to do a simple derivation,The second is carries on the modelling to the chassis,finally,programming and debugging Commissioning Program,Analysis and concluded.This involved the wave equation initial conditions, the boundary conditions and wave equation solving problems.How to use C + + language in MinGW simulation electromagnetic leaked.Through this paper,reader also can be attempting to use method in paper,to do a simple calculation of the electromagnetic leak about your pc,know more self computer.
