Description
Summary:In this letter, the reduced-order technique, originally introduced by the authors, is extended to the design of complex waveguide structures. The model-order reduction (MOR) is applied to the coupled integral equation formulation, and it is based on Krylov subspace projection, singular-value decomposition, and a forward-backward iterative method. The technique has been successfully applied to the design of a wideband corrugated horn operating in Ka band.
