Magnetostatic Surface Wave Nonreciprocal Tunable Bandpass Filters

摘要

A nonreciprocal tunable bandpass filter includes a transducer comprising parallel coupled conductive lines; and a ferrite body having at least two opposing parallel edges, the ferrite body disposed over the microstrip transducer such that the parallel edges of the ferrite layer are tilted at a non-zero angle Θ with respect to the parallel coupled microstrip lines of the microstrip transducer.
