Özet

A full-wave space-domain mixed potential integral equation (MPIE) approach, discredited with the method of moments (MoM) and used in spatial-domain closed-form Green's functions, is presented for the numerically efficient analysis of some passive microwave structures in planary layered medium. The spatial-domain Green's functions for the vector and scalar potentials, represented by the Sommerfeld integrals, are approximated by closed-form expressions and used in the solution of the MPIE by the MoM. By using the closed-form Green's functions into the MoM, the computational efficiency of the MPIE MoM is significantly improved. The main advantage of the MPIEMoM technique allows a large variety of printed circuit structures to be characterized. The accuracy and the efficiency of the technique is demonstrated at the example of dual-mode filter configurations consist of coupled microstrip open-loop resonators, and compared the results with those obtained from commercial EM software such as EM Sonnet.
