Abstract :
A magnetic field tunable barium hexaferrite (BaM) dielectric resonator that could potentially function as an isolator operating at 82-90-GHz has been designed and characterised. A 30-GHz increase in operating frequency was achieved by using dielectric resonances instead of the usual ferromagnetic resonance. The dielectric resonance and the operating frequency of the isolator can be tuned by 0.84-MHz/Oe almost linearly with an applied magnetic field.
