In this paper, a generalized two-dimensional formulation for solving planar guiding structures is presented. The formulation is capable of analyzing guiding structures consisting of an arbitrary number of slots and strips with arbitrary width, thickness, and conductivity in a full-wave regime. Integral equations solved with the method of moments in the spatial domain are used in the analysis. All information related to the fundamental modes of the guiding structure are available from the presented theory. These information include (for each mode) the propagation constant, electric and magnetic current distribution, modal power, and the characteristic impedance. Numerical results for a number of planar guiding structures are presented, which validate the proposed theoretical formulation.
