Abstract :
It is well known that structures built around electrodynamically coupled open waveguides are actively engaged in microwave engineering for directional couplers, filters, antennas, etc. The wave propagation problem for a pair of cylindrical slot/strip (CSIL/CStL) lines has already been rigorously solved. The present work examines the numerical characteristics of the waves in a structure. The considered boundary value problem is solved by the Riemann-Hilbert problem technique using the additional theorem for the cylindrical function. The dispersion characteristics of the waves for some modifications of coupled CSIL/CStL and the effect arising from the mutual interaction of single lines are analysed.
