Abstract
An axially symmetric permanent magnet structure with tunable longitudinal fields is described wherein selected radial magnet sectors in a truncated Halbach array configuration are tiltable. The tunable magnet structure is particularly useful in Faraday devices, such as Faraday rotators, Faraday mirrors, optical circulators and optical isolators.
