A new design method for microwave cascade networks

An efficient method for the analysis and design of microwave cascade devices is presented. Complete control of electrical and geometrical parameters, together with the possibility of minimizing a cost function gradually imposed, permits the synthesis of sophisticated microwave components. The generalized scattering matrix (GSM) of a cascade network is computed using a new recursive formula. A cascade of discontinuities is computed starting from the GSM of the load and going back, step by step, to the source until the last discontinuity is reached. A comparison between the proposed method and the classic GSM approach is given. A novel network synthesis procedure is described, comparing the proposed method with other procedures in the design of a circular polarizer in a square waveguide.<>
