A Broad-Band Ferrite Reflective Switch (Correspondence)

Several types of reflective ferrite switches have recently been described in the literature. These have typically made use either of the Faraday rotation effect or of a waveguide cutoff induced by a transversely-magnetized ferrite slab. A different and very simple type of switch, which exhibits similar reflective behavior, may also be obtained by the use of a short section of heavily-loaded (or filled) coax, stripline, or waveguide.
