However, in order to overcome these difficulties and to increase the efficiency of these well-known solutions the use of a new technology of Impedance coupling
will be also explored.
For every routed signal, we have to ensure that we have a proper return path that is located where we want it and that we don't obstruct already created paths, because signals sharing a part of the return path have common impedance coupling
(energy coupled from one signal to the other).
The resonant frequencies of the resonators are chosen and arranged such that the resonators together operate to provide a low impedance band in the frequency spectrum within which low impedance coupling
between the common circuit ground and the ground potential is achieved.
