The technique uses a surface integral equation formulation to treat both metallic and dielectric objects inside the component structure. In order to avoid the relative convergence problem of other techniques based on mode matching, a novel port treatment is used. The technique is based on the application of the extinction theorem using the spatial representation of the Green's functions and image theory. Different complex H-plane structures are analyzed, including microwave bandpass filters with elliptic transfer functions and waveguide bends with dielectric posts. Results show the high accuracy and versatility of the new technique derived %K Teoría de la Señal y las Comunicaciones %K Métodos de la función de Green %K Paso de banda integral %K Ecuaciones integrales %K Filtros de microondas %K Red multipuerto %K Funciones de transferencia %K Componentes de ondas guía %K Discontinuidades de ondas guía %K Green's function methods %K Band pass integral %K Equations integral (EI) %K Microwave filter %K Transfer functions %K Waveguide components %K Waveguide discontinuities %K Multiport network %~ GOEDOC, SUB GOETTINGEN
