capacitive coupling is the transfer of energy within an
electrical network or between distant networks by means of displacement currents induced by existing electric fields between circuit(s) nodes. This coupling can have an intentional or accidental effect. In its simplest implementation, capacitive coupling is achieved by placing a
capacitor in
series between two nodes. In its general form the coupling is described by a capacitance matrix
Cij. Where
Cii are
self-capacitance coefficients and
Cij i≠j are
mutual capacitance coefficients.
