Abstract:
A tunable low-loss microwave component, adapted to be in communication with a power source producing an applied voltage and an applied current, comprising:at least one ferroelectric (FE) material, wherein the at least one FE material changes electric permittivity with the applied voltage, and at least one ferromagnetic (FM) material, wherein the at least one FM material changes magnetic permeability with the applied current, such that the tunable microwave component is tunable to at least a first frequency when the component is a non-bias state in which the power source applies no voltage or current, and tunable to at least a second frequency when the component is in a bias state in which the power source applies voltage and current, and wherein the tunable microwave component has a constant characteristic impedance at the first and second frequencies.
