Microwave magnetic thin-film devices

The author reviews the current status of magnetic film technology and then summarizes the state-of-the-art and remaining unsolved problems of each of the three major application areas: analog signal processing devices, tunable filters and oscillators, and control components. Two major thin-film approaches are covered: magnetostatic-wave (MSW) devices and thin-film implementations of bulk-ferrite devices. Promising research directions are identified.<
