Tunable Magnet Structure
US Patent:
8547636, Oct 1, 2013
Filed:
Nov 3, 2010
Appl. No.:
12/938567
Inventors:
James Frederick Niessink - Suttons Bay MI, US
Assignee:
Electro-Optics Technology, Inc. - Traverse City MI
International Classification:
G02B 27/02
US Classification:
35948402
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.
