  • EMI/RFI filter including a ferroelectric/ferromagnetic composite
    Patent number: 6346865
    Abstract: An EMI filter (10) that makes use of a ferroelectric-ferromagnetic composite, member, or slab (12) in connection with capacitive and inductive elements. The geometrical structure of the filter (10) is such that the mutually orthogonal electric fields and magnetic fields generated by the capacitive and inductive elements penetrate the volume of the composite (12). In some designs, capacitive plates (14, 18, 32, 34) are split to avoid setting up eddy currents in the plates (14, 18, 32, 34) which oppose the penetration of magnetic flux through the composite (12). Various structural designs can be provided to define the capacitive elements and the inductive elements in different configurations relative to the composite to satisfy the desirable requirements.
