Abstract
The common mode coupling from PCB sources to cables is one of the most significant emission mechanisms. We obtain a design expression for the common mode coupling inductance of a PCB trace inside a cavity from the cavity field, which is excited by this trace. This reveals a general relation between the coupling of PCB sources to a cavity and the common mode coupling to cables. In a second step we show that the coupling of a PCB to a parallel plane cavity can be obtained from the PCB near field.
