A program for performance assessment of corrugated waveguide transmission lines

Long corrugated waveguide transmission lines are commonly used in nuclear fusion experiments, both for heating and diagnosing plasmas. A common task for designers is computing the polarization along the waveguide and the power transmission, including ohmic and mode conversion loss. Moreover, designers need often specify alignment and positioning tolerances. The program described in this report aims at fufilling these needs and be of use to microwave engineers facing these tasks. Since polarization calculation is independent on the rest, the program can also be used for computing on-axis polarization along quasi-optical transmission lines. It is freeware and available in Fortran 90 source form at IFP's website alonside this report. Users are kindly requested to cite this report in their papers.
