Systematic Characterization of Isotropic Unilateral Finlines for Millimeter-Wave Applications

In this work, an efficient characterization of finline structures is proposed. Based on the Galerkin`s technique in the modal domain, its uses the mathematical operator formalism to determine the dispersion parameters and the characteristic impedance from the power-voltage concept. By selecting trial functions with edge effects, the obtained numerical results are successfully compared with those published.
