Abstract
A device for unidirectional propagation of microwaves comprises a resonant microwave structure arranged to transmit microwaves between two ports and a magnetic source arranged to provide a generally static magnetic field and to have a resonant frequency distinct from that of the microwave structure, which is disposed adjacent the microwave structure so as to be located in presence of electromagnetic fields emanating from the transmitted microwaves such that the magnetic field interacts with the electromagnetic fields of the microwaves so as to form a set of hybridized resonant frequencies at which zero intrinsic damping exists, one of the set of hybridized resonant frequencies being a real eigenvalue providing the unidirectional propagation from one of the first and second ports to the other. A related method comprises arranging the magnetic source at a prescribed position where the real eigenvalue matches the frequency of an input signal applied at a selected port.
