Abstract
A two track surface wave arrangement has improved selection property resulting from crosstalk signals of parasitic transmission paths within the arrangement being suppressed. What can be achieved with a displacement of the surface wave arrangement of one track relative to that of the other track by a dimension of nearly half a wavelength is that crosstalk signals mutually cancel on the basis of interference without affecting the useful signal.
