Supply chain risks are greatly reduced in our domestically produced Self-biased Circulators and Isolators™ by using readily available raw materials, rather than rare-earth metals. Offering planar and monolithic construction, our innovative devices also withstand levels of shock and vibration that far exceed those attainable by microstrip permanent magnet solutions whose magnets are known to detach under harsh conditions, such as missile launches. Using this material as the basis for our Self-biased Circulators and Isolators™, Metamagnetics has been able to demonstrate 90% reduction in size and weight over traditional microstrip permanent magnet isolators and circulators. Our innovative material is created by aligning its magnetic grains and then processing it at high temperatures to create an ultra-dense compact that is free of defects and voids-and which ultimately acts as a magnet itself. These innovative devices enable developers to produce high power, broadband radar systems that achieve their goals for size, weight, power and cost reductions (SWaP-C), while also enabling a variety of novel system design and surface mount installation approaches. Metamagnetics has developed a new substrate that has enabled our robust, high-performance, and miniaturized Self-biased Circulators and Isolators™.
