Specially designed 3-terminal elements called flow-junctions (FJs) and ‘reverse flow diverters' (RFDs) are shown to have useful amplifying properties which are often unrecognised. These are described by relating the devices to ideal network elements using an indefinite circle diagram. The FJ is useful between two transformer-like states and at the mid-point of this range its utility is described by its impedance matrix. A circuit using an RFD is shown to give a large-signal power gain which compares favourably with an equivalent circuit using a vortex device.
