Abstract :
The design and analysis of a new class of electric field-tunable ferrite-ferroelectric microwave bandpass filter is discussed. The tunability is possible through magnetoelectric interactions. When the composite is subjected to an electric field, the mechanical deformation due to piezoelectric effect manifests as a magnetic field shift in the ferromagnetic resonance for the ferrite. The electrical tuning is much faster than traditional magnetic tuning and has practically zero power consumption.
