5. circulator
   a passive device having three or more ports in which the power entering any port is transmitted to the next port according to a given order of sequence NOTE - By reversing the biasing field, the order of sequence is reversed. This property may be used to switch electromagnetic energy.

6. circulator
   a multiport device in which the incident wave to any port is transmitted to the next port according to an order of sequence determined by the sense of a static magnetic biasing field NOTE 1 - By reversing the magnetic biasing field, the order of sequence is reversed. NOTE 2 - This property may be used to switch electromagnetic waves.

7. Circulator
   A `circulator` is a passive non-reciprocal three- or four-port device, in which microwave or radio frequency power entering any port is transmitted to the next port in rotation (only). Thus, to within a phase-factor, the scattering matrix for an ideal three-port circulator is :<math>S = egin{pma...
