Data for: "Dispersion Curve of the Helically Corrugated Waveguide Based on Helicoidal Coordinate Transform"

This dataset contains two sets of data, both in txt file format. One is the disperions curve obtained from the 2D simulation, and the header in the txt file marks that the first column is the normalised wavenumber and the second is the frequency in GHz. The other file is the 3D simulation results exported from the CST simulations with different phase shift values. The txt file itself is well labeled to show the first column is the mode index and the second column is the frequency of the mode.
