Annotation: New formulas and graphs for modal parameters are given, which are necessary for the synthesis of unequal coupled lines with arbitrary dielectric filling. The choice of modal parameters, such as characteristic impedance, coupling coefficient, modal voltages and dielectric constants, as initial data for the calculation allows optimal synthesis of the coupled line parameters, and followed determination of the geometric dimen-sions of the structure.

Keywords: coupled lines, dielectric filling, synthesis, pul parameters, modal parameters, inhomogeneous dielectrics, coupling coefficient
