Conclusions
It was demonstrated that for the usually employed widths of the shield in MSL a parasitic quasi-LM10 wave may propagate besides the working quasi-TEM wave; the quasi-LM10 wave interacts with the working wave in the inhomogeneities of the line and may disrupt the normal operation of devices having MSL. The propagation constants of these two lower wave modes may be determined comparatively simply with an accuracy of the order of 1% by means of the first-approximation dispersion equation derived in the present paper. The system of linear algebraic equations derived in the present paper may serve for the analysis and calculation of the characteristics of the higher wave modes.
