Self-Biased Circulator and Isolators

Embedded advanced material that eliminates permanent magnets for lighter, more efficient solutions.

Get Spec Sheet
Hexagonal device labeled METAMAG with three connected gold-colored T-shaped components around a central circle, described as a self-biased circulator.

Compact

Highly compact planar and monolithic solution with a reduction of up to 90% in size and weight by eliminating the need for bulky magnetic components.

Shock and Vibration Resistant

Inherently strong shock and vibration resistance by eliminating the magnetic component that can shift, degrade, or detune under mechanical stress.

Secure Supply Chain

Magnet-free self-biased circulators strengthen supply chain security by eliminating reliance on rare-earth magnets that often face sourcing volatility, export constraints, and long lead times.

Simplified Integration

Drop-in behavior and minimal interface requirements make these circulators easier to incorporate into diverse architectures or platforms.

Monolithic Design

Monolithic form factor is inherently compatible with automated assembly processes, improving manufacturing reliabilty and throughput.

US Designed and BUILT

Designed and assembled in the USA ensuring full domestic control over supply chain security.

Our Solution

Metamag leverages its proprietary magnetic technology to create resilient and compact rare-earth-free products.

“Rare earth magnets power everything from electric vehicle motors and wind turbines to missile defense systems. Large portions of the supply chain are controlled by China.”

Comparison of a Self-Biased Circulator to a traditional Circulator

Metamag's self-biased circulator demonstrates 90% reduction in size and weight over the conventional permanent magnet circulators. 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.
