Abstract :
The present paper is focused on the wave characteristics of screened cylindrical strip and slot lines (SCMSL and SCSIL) analyzed with the rigorous electrodynamical Riemann-Hilbert method. The latter provides an adequate numerical-analytical approach whose solution involves no limitation on the structure geometrical parameters. The present work is addressed to the dispersion characteristics of SCMSL, with various dielectric fillings and the effect of the transformation of the SCSIL waves into SCMSL ones as the slot is widened. An approximate analytical formula evaluating the phase constant coefficient of the principal wave of the SCMSL has been specially obtained.
