Abstract : A microwave coupling device functioning as an isolator and as a switch. The device is constructed by placing a magnetically ordered crystal characterized by a uniaxial magnetic anisotropy field, such as a ferrite, through mutually aligned holes in a pair of orthogonally coupled transmission lines. No external magnetic field bias is required for nonreciprocal transmission of microwaves from one transmission line to the other. The preferred direction of propagation can be reversed by application of a transient magnetic field. (Author)
