A New Mesh Reduction Technology for the Method of Moments Modelling of Planar RF and Microwave Interconnects

This paper describes a new mesh reduction technology that significantly increases the electromagnetic modelling efficiency of planar RF and Microwave interconnect structures. This technology reduces the redundancy in the method of moments equations due to the geometrical complexity of the structure. It comprises a generalization of the basis functions used in the discretization of the surface currents. The generalized basis functions allow for a more efficient meshing of complex geometrical structures in terms of polygonal shaped cells. The increased simulation performance is demonstrated for a complex microwave package interconnection structure.
