Abstract：In this paper, the finite radial thickness tape helix is replaced by the same thickness vacuum layer laid in an infinite thin tape helix. The effect of position of the infinite thin helix on the dispersion and coupling impedance is studied by field analysis and computer simulation. The computed and simulated results are compared to those measured. As a result, if the infinite thin helix lay in the middle of the vacuum, the three results of dispersion and coupling impedance are good agreements when laying an infinite thin tape helix in the middle of the same thickness vacuum layer.
