In all circuits both common-mode (CM) and differential-mode (DM) currents are present. Both types of current determine the amount of RF energy propagated between circuits or radiated into free space. There is a significant difference between the two. Given a pair of transmission lines and a return path, one or the other mode will exist, usually both.
