Abstract :
In the present paper various class of helix slow wave structures, right from S-band to Ka-band, dielectric loaded and segment loaded have been analyzed to obtain the dispersion and impedance characteristics using MAFIA and tape helix model HELTAPE and the results compared. For the MAFIA simulation ten turns of helix were modeled in the cylindrical coordinate system by varying axial and azimuthal coordinates consistent with the formula of a circular helix.
