Abstract :
A very simple, yet rigorous and efficient model for the full-wave characterization of hybrid T-junctions is proposed. The model is based on a suitable segmentation of the structure in conjunction with the admittance matrix description. When suitable modal expansions of the Green´s functions are considered, a very high numerical efficiency is obtained. Numerical simulations show excellent agreement with measured data.<>
