Abstract: PURPOSE: A nonreciprocal circuit device is provided to reduce in size of the isolator and eliminate a conversion loss. CONSTITUTION: A nonreciprocal circuit device includes conductive films(2a,2b) that define a slot(3a) on the top of a magnetic member(1) having ferromagnetic characteristics. On the bottom of the magnetic member(1), other conductive films(2c,2d) that define an opposing slot(3b) are formed. An external DC magnetic field is applied substantially parallel to the magnetic member(1) and substantially perpendicular to the slots(3a,3b). Resistive films(4a,4b) are formed alongside the slot(3a) on the top of the magnetic member(1). When a signal propagates in the direction from port #2 to port #1, the electromagnetic field of a planar dielectric line mode is localized in the direction of the resistive films(4a,4b). Electrical power is consumed by the resistive films(4a,4b), so that the signal is prevented from propagating. When the signal propagates in the direction from port #1 to port #2, no loss is caused by the resistive films(4a,4b). Therefore, the signal is transmitted with low loss.
