A Foster-Type Partial-Element Equivalent Circuit Model for the Modeling of Wire Structure in Rectangular Enclosures

For the modeling of wire structures in rectangular metallic enclosures, a Foster-type partial-element equivalent circuit model is presented. The model is based on the electric field integral equation of the wire structures. The integral equation is converted to a circuit network adopting the method of moment and the Kirchhoff's voltage law. The dyadic Green's functions for a three-dimensional (3-D) rectangular cavity are used. The circuit elements and the controlled sources are realized by the Foster-type circuit model. Application examples validate the accuracy and efficiency of the presented model.
