Abstract

A feather-edge conductive pattern is sandwiched between two ferrite bars so s to cause different degrees of residual magnetism in the bars. Two other blocks of materials having relative high dielectric constants sandwich the ends of the bars, and the whole device is inclosed in a waveguide which will have variable phase shifts in accordance to the residual magnetism of the bars.
