Análisis multimodal eficiente de uniones planares entre guías arbitrarias: aplicación a la excitación coaxial de dispositivos

In this paper, a novel technique for the rigorous multimodal analysis of arbitrary planar waveguide junctions is presented. The proposed method, based on the resolution of a magnetic-type integral equation, turns out to be very efficient from the computational point of view, thus facilitating its integration in modern CAD tools oriented to the design and optimization of guided passive microwave devices. Different types of coaxial fed planar waveguide junctions have been analyzed thus fully validating the proposed technique
