ABSTRACT:
A delay-line has two essentially identical distributed parameter delay-line sections that have series connected solenoidal coils and mutually parallel axes. The winding directions of the two coils are such that an external observer traveling along the series connected coils from one free coil-end to the other will observe a winding direction reversal in going from one section to the other. Thus a uniform unidirectional magnetic field having a component parallel to the section axes will produce induced voltages in the two coils that are of opposite polarity and no net induced voltage will appear between the free ends of the series connected coils.
