ABSTRACT:
A transformer or coupling device having differing impedances and comprising a pair of conductors each constructed and arranged to have a standing wave in one which is a mirror image of the standing wave in the other so that the impedance varies from near zero at one end of the conductors to a maximum near their center. The transformer having an impedance matching that of one device to be coupled and having output terminals connected to points on the other conductor having an impedance matching that of the other device to be coupled.
