Scope

1.1 This standard (Part XLI) covers definitions of terms applicable to passive, non-reciprocal components for circuits and transmission lines, that is multipart devices in which the propagation properties depend upon the direction of propagation of electromagnetic energy through the device.

NOTE - Passive, non.reciprocal components usually utilize the gyromagnetic effect in a medium, for example, a ferrite, whose magnetic properties are expressed by a tensor permeability. Therefore, the term gyromagnetic device may also be used for such components. On the other hand, not all ~yromagnetic devices are non-reciprocal, since the wave propagation properties depend upon the spatial arrangement of the high - frequency and biasing magnetic fields.

The biasing magnetic field, which may sometimes be due to remanent ~agnetization only, may be either static or dynamic. Components in which pulsed external fields are used to change the state of remanence (and thereby the biasing field) are sometimes called latching devices.
