From design to market of electronic systems: EMC engineering Preface

Electromagnetic Compatibility (EMC) concerns with device - device interaction. More and more electrical - electronic devices have to operate in the same or close frequency bands and within closer distances, such as onbody health, telecommunication, and entertainment devices, wireless office equipments, etc. In terms of EMC effects near-field complex interference is of interest. A device or a system is said to be (electromagnetically) compatible if it does not cause interference with other systems, if it is not susceptible to emissions from other systems, and finally if it does not cause interference with itself. Therefore, the goal is to produce less interfering and less susceptible (i.e., highly immune) devices. An EMC problem has three components; the interfering source, the victim and coupling paths. Undesired interference may be eliminated by one of these three ways: (i) by suppressing the emissions at the source, (ii) by making the victim less susceptible (highly immune), and (iii) by removing the coupling path
