The technique benefits from the symmetry of the structure in order to reduce the dimensions of the problem from three to two dimensions. For the first time, this technique formulates the waveguide capacitive discontinuity problem as a 2D scattering problem with oblique incidence, com- bined with an efficient calculation of the parallel plate Green's functions. Results for a capacitive impedance transformer are successfully compared with measurements for validation of the proposed theory. %K Teoría de la Señal y las Comunicaciones %K Lowpass filters %K Waveguide filters %K Capacitive waveguide circuits %K Filtros de bajo paso %K Filtros de guía de onda %K Ecuaciones integrales %K Circuitos de guía de onda %K Integral equation (IE) %~ GOEDOC, SUB GOETTINGEN
