Self-biased ferrite circulator devices have been demonstrated and thus far exhibit high loss and poor isolation, making them unsuitable for practical applications. The main reason for less than satisfactory performance and high frequency of operation lie in the unacceptable quality of hexagonal… More

The development of a high performance ferrite material with capability of 1 to 7 MHz 3dB frequency is pursued. The proposed ferrite material consists of MnZn-ferrite particles with a thin coating of NiZn-ferrite. The role of the NiZn-ferrite coating is to suppress eddy currents, by providing an… More

Metamagnetics proposes to address the limitations of currently available commercial-of-the-shelf tunable microwave filters in terms of insertion loss, linearity, tuning speed, etc. by developing innovative voltage tunable multiferroic microstrip filter technology. The proposed concept offers the… More

Self-biased ferrite circulator and isolator devices have previously been demonstrated and discussed in the literature. While operation without biasing magnets was verified, all the prototypes constructed thus far exhibited relatively high loss and poor isolation, which made them unsuitable for… More

The development of switch mode power supplies is constantly challenging the ferrite industry to produce new, high-quality ferrite cores capable of operating at increasingly higher frequencies and low loss. Furthermore, it is important to reduce the power losses of ferrite cores used in transformers… More

Modern active electronically scanned phased array radars provide outstanding capability but are unfortunately expensive. To a large degree, this results from the need for power and low noise amplifiers at each antenna element. A promising alternative architecture shares the amplifiers among many… More

Microwave oscillators based on ferrimagnetic precession and excited with a fast-rise time pulsed input have been proposed to achieve high power microwave (HPM) generation. The properties of ferrite materials utilized in such systems impose limitations on performance, including peak power capability,… More
