Abstract

Electromagnetic compatibility is getting more and more interest as soon we are speaking about electronic devices. EMC must be planned, calculated, simulated, and measured to ensure that the device can work in the environment of other devices and does not disturb other devices by unwanted interference. In complex devices, simulation methods due to the large number of elements and complicated operations can be extremely costly and time consuming. We should consider how is it possible to reduce these costs, for example with simplifying our simulation terminology. This paper explains a general theory about using premeasured EMC properties in simulation to find out how a complex system (containing many devices) will work out. This theory is about how different radiated electromagnetic waves have effects on other devices. Electromagnetic compatibility (EMC) standards have been developed to test and limit unintentional coupling to and from electronic devices (interference), but not developed to deal with more devices crowded in a smaller environment. If we handle the different devices as antennas, in the simulation environment we must not deal with their internal structure and operation (till we need information of the inside). This way simulation time can be drastically reduced.
